How to Make a Podcast Ad with Murf

Most “AI voiceover for a podcast ad” posts skip the two facts that actually decide the file. First: a twenty-second host-read is not a definition, and it is not a voicemail. The break lives on an enclosure a car stereo will play — either before the first question or between two chapters. A landing-page explainer and a callback number are the wrong clocks. Second: a free-tier preview is not a track you drop on a monetized feed. This guide is the working path for the spoken host-read — write the sponsor, pick a voice, pace the break, export audio — using the one voice studio we can send you to with a live affiliate hop: Murf.

When Murf is the host-read tool — and when you want an explainer, a lesson, or a booth

Use Murf when the open is a short, first-person sponsor you will regenerate. A twenty-second pre-roll before the cold open. A mid-roll of the same offer after the first chapter. A recut of both files next week when the trial length or the URL changes. The economic case is the recut: edit the sentence, generate again, replace the clip. You do not re-book the host for twenty seconds.

Skip Murf if the file is a 60–90 second definition. That is How to make an explainer voiceover with Murf — an ordinary guide link, not a second money hop. Skip both if the missing piece teaches one step on slides. That is How to make a course lesson voiceover with Murf. Skip both if the remaining job is a missed-call drop. That is How to make a sales voicemail with Murf. Skip a stock library voice if listeners would take the break as the named host and you do not have a clone yet. That is How to clone your voice for YouTube.

The seven-step Murf host-read podcast ad

1. 01

   Write a 15–30s host-read sponsor — a pre-roll open or a mid-roll break

   A host-read podcast ad is the show talking to the listener as if the host paused the conversation. It is not a third-person announcer sting, not a 60–90s “what this is” explainer, not a 2–4 minute taught step, and not a 20–30s missed-call drop. Time both slots out loud on headphones and in a car. Fifteen seconds is “this episode is sponsored by,” the product name, and one next step said the way a subscriber should hear it. Thirty seconds is a first-person beat the listener already lives, one proof a stranger can check, and a URL or code spoken at 1.2×. A pre-roll sits before the conversation starts — “before we get into it.” A mid-roll sits between two chapters — “we will be right back.” Spell the brand and the destination the way they should be heard. If you wanted a 60–90s concept cut, that is the Murf explainer how-to. If you wanted a 2–4 minute slide teach, that is the Murf course-lesson how-to. If you wanted a callback number on a phone, that is the Murf sales-voicemail how-to. If you wanted a third-person announcer mid-roll, that is the Murf podcast-ad-voiceover how-to.

2. 02

   Confirm a first-person studio read is the right podcast-ad format

   Use Murf when the episode already exists — the interview is locked, the pre-roll or mid-roll mark is on the timeline — and the missing piece is a directed first-person sponsor you can recut when the offer changes. Skip Murf if the file has to sound like the named host. That is a live take or a clone, and Murf does not sell self-serve cloning. Skip it if the remaining job is a 60–90s definition on a diagram. That is the explainer how-to, an ordinary path on this site, not a hop here. Skip it if the remaining job teaches one step on slides. That is the course-lesson how-to. Skip it if the remaining job is a missed-call drop with a phone number. That is the sales-voicemail how-to. Skip a stock library voice if listeners would take the break as the actual host. Record the host, or stop.

3. 03

   Open Murf Studio — the voiceover editor, not an avatar desk

   Murf Studio is where you write the script, pick a voice, add media, preview, and export. That is the product this page is written for. Synthesia (synthesia.io) is a different company and a different job: a presenter on camera. Synthesys (synthesys.io) is a third company. Mixing the names is the expensive mistake. This page sends you to Murf only.

4. 04

   Sit on a plan that can download the file before you treat it as a paid break

   Free is an audition: Murf’s published pricing page gives a short generation allotment and no downloads, and it lists no commercial rights. Paid Studio plans are where the Export menu becomes a file you can drop on an episode or into an ad slot — and where commercial rights start. Voice generation is metered in hours; unused time does not roll over. Confirm the live grid on Murf’s pricing page before you treat a render as a feed asset. We do not invent a rate card or a commission here. Custom voice clones sit on Enterprise via sales. Do not buy Creator hoping the stock narrator becomes the host.

5. 05

   Pick one conversational stock voice from the Voices and Language Library

   Filter the library by language, accent, gender, age group, voice style, and use case, then preview before you apply a voice. Murf’s first-voiceover help is blunt about use case: an e-learning or documentary read is the wrong cast for an advertisement or marketing video. A host-read should sound like a calm closer sitting next to the listener, not an LMS drone and not a skippable bumper. Filter toward a marketing or advertisement voice with a conversational style — first-person, even, car-stereo clear. Cast one voice and keep it for the pre-roll, the mid-roll, and the recut when the offer changes. Do not clone a real host unless you have written consent and an Enterprise conversation. One voice. One offer family.

6. 06

   Paste the sponsor as one piece, generate, then pace it for a podcast break

   Paste the 15–30s host-read into the text editor. Murf’s Paste Preference screen can Split Script by Paragraphs, Split Script by Sentences, or Don’t Split. That same first-voiceover help calls out short advertisement voiceovers as the reason to leave the copy in one piece. Don’t Split so the product name and the visit line do not break mid-offer. Generate the pre-roll and the mid-roll as their own projects — an open should not inherit a mid-show pause map. Click the empty play control to render; Murf’s help says that button turns black when the take is ready. Preview a block, then the project — play exists at the sub-block, the block, and the project. On a selected block, Murf’s published Studio settings include tone, speed, pitch, pause, the pronunciation library, variability, and emphasis. Speed and pitch sliders are documented from −50% to +50%, per block or across the project. Put the brand and the URL in the pronunciation library before you blame the voice. Add a pause after the sponsor line and before the CTA — the pause menu lists Extra Weak (0.25s) through Extra Strong (1.25s), plus a custom pause from 0.1 to 5 seconds, or the [pause Xs] syntax. Word-level Emphasis is published on Business and Enterprise. If that control is not on your plan, split the sentence and re-render the block. Do not invent a slider we cannot see on the public help.

7. 07

   Export audio, then drop the file on the pre-roll or mid-roll you already have

   Open the Export menu. Voice export on paid plans lists MP3, WAV, and FLAC (plus telephony a-LAW / μ-LAW if that is actually the job). Quality steps on that help page are Low (8 kHz), Medium (24 kHz), and High (48 kHz), mono or stereo. For a podcast-ad handoff, High WAV or MP3 is the usual file. We do not invent a pre-roll, mid-roll, or DAI preset inside Murf. Export the audio, then put it on the episode you already have — line the first word to the break mark, leave a breath after the host stops, leave a breath before the host returns, and export that timeline as the enclosure your RSS host will take. If your network inserts ads dynamically, hand them the standalone file and confirm the live slot spec on that host; we describe the drop because insertion UIs move. Name the files so the next offer change is obvious: cinderlane_podcast_preroll_en_v1 and cinderlane_podcast_midroll_en_v1. When the offer or the URL changes, edit the block, export v2, replace the clip. Confirm commercial terms on the plan you exported from, then say the break is an ad out loud. That spoken sponsor line is separate from the vendor license. You need both.

Host-read podcast ad vs an explainer vs a sales voicemail

“AI podcast ad” is a search, not a product. The decision is the format. The Murf column matches Studio help and the live pricing page as of August 2026. The explainer and voicemail columns are the other Murf briefs, not a second Try button.

The script is a 15–30 second host-read, spoken twice

Do not write a cold open for a documentary. Do not write “what this is, why it matters, what to do next.” Do not leave a callback number. Time the copy out loud, on headphones and in a car, with the sound on. Fifteen seconds is enough for the sponsor line and one click. Thirty seconds is a first-person beat, the product, one proof, and a CTA. Longer than thirty and you are writing a different break.

A working mid-roll, spoken at a normal pace — roughly twenty seconds if you leave the pauses a car stereo needs:

We will be right back. I used to rebuild next week’s guest list in a thread at 11pm.

Cinderlane is one page for the week. I pin the slot, it texts the guest the time, and I stop asking the same question in Slack.

This break is sponsored by Cinderlane. The week lives on one page. Cinderlane dot com slash podcast.

The pre-roll is not that paragraph with “before we start” taped on. Write it as its own twenty seconds — still first-person, still an ad, still a stock narrator:

Before we get into today’s conversation — a word from the people who keep this show’s week on one page.

I pin the guest slot in Cinderlane. It texts them the time. I stop rebuilding the calendar in a thread.

This episode is sponsored by Cinderlane. Cinderlane dot com slash podcast.

Spell the words the voice should say. “The week lives on one page,” not a logo lockup. “Cinderlane,” the way you want it heard, not the way the domain is spelled. Put that name and the URL in Murf’s pronunciation library once, then keep the voice. A library narrator that survives your product title is worth more than an energetic read that flubs the destination.

Keep one voice for the pre-roll, the mid-roll, and the recut. Murf’s stock library is a set of studio narrators: clean, even, consistent across a week of paid breaks. That consistency is the product. Emotional range is not why you are here — if it is, the comparison is ElevenLabs vs Murf vs Synthesys. Full product notes live in our Murf review.

Pick a voice. Paste the sponsor. Direct the take to the break.

Open the Voices and Language Library. Murf’s Studio basics page lists language, accent, gender, age group, and use case. First-voiceover help also lists voice style. Preview before you apply. The first-voiceover page is explicit that use case is the cast — an e-learning or documentary voice is the wrong read for an advertisement or marketing video. Filter toward a marketing or advertisement voice with a conversational style. A host-read is the show talking, not the lesson and not the missed call. Pick one. Keep it.

Paste the mid-roll as one piece. Murf’s Paste Preference screen offers Split Script by Paragraphs, Split Script by Sentences, or Don’t Split. That same help page calls out short advertisement voiceovers as the reason to leave the copy in one piece. A 15–30s host-read should not break between the product name and the visit line unless you want that breath. If you do want a beat, add a pause — do not hope a sentence split lands it. Paste the pre-roll as its own project. An open should not inherit a mid-show pause map.

Click the empty play control to render. Murf’s first-voiceover help says that button turns black when the take is ready. Preview exists at three levels: the sub-block, the block, and the project play button on the timeline. Listen on headphones and in a car, not just studio monitors. A host-read dies when the sponsor line is mumbled the same way a Reel dies in the first second.

On the selected block, the published voice settings are tone, speed, pitch, pause, pronunciation library, variability, and emphasis. Speed and pitch move from −50% to +50%, on one block or across the project. Put product names and URLs in the pronunciation library before you re-roll. Pause is the break-specific control: Extra Weak (0.25s), Weak (0.5s), Medium (0.75s), Strong (1s), Extra Strong (1.25s), a custom pause from 0.1 to 5 seconds, or [pause Xs] in the script. A beat after the sponsor line keeps “the week lives on one page” from running into the proof. Do not put that beat before the listener hears that this is an ad.

Word-level Emphasis is the one control we will not pretend is on every plan. Murf’s speed-and-pitch help puts that tool on Business and Enterprise. If you cannot open it, split the sentence and regenerate the block. Do not invent a slider name we cannot see on the public page. Variability is listed in Studio basics; use it only if a flat read is the problem, then listen again — a 20-second host-read should not start performing.

The timeline is still useful on a short file. Voice blocks, media tracks, and background audio sit on one surface. If you already have a sting or a bed, drop it there and watch the preview with the VO before you export. Stretch a block when the read has to hold a breath. That is direction, not a booth session.

Export audio, then put the file on the break you already have

The Export menu is the gate. Murf’s voice-export help is explicit: paid plans. Formats on that page are MP3, WAV, and FLAC, plus a-LAW and μ-LAW for telephony. Quality steps are Low (8 kHz), Medium (24 kHz), and High (48 kHz), 16-bit, mono or stereo. For a podcast-ad handoff, High MP3 or WAV is the usual file. We do not invent a pre-roll button, a mid-roll button, or a DAI preset inside Studio. The break is the episode you already have — a locked interview, a chapter mark, an ad slot — plus this VO.

Import the WAV onto a dedicated voice track. Line the first word to the break mark. On a pre-roll, leave a breath before the host’s first line so the visit line is not swallowed. On a mid-roll, leave a breath after the host stops and before the host returns. If you use a music bed, duck it under the narration so the product name is the loudest thing in the first five seconds — or mute the bed for the length of the read. Export that timeline as the MP3 or M4A your RSS host will take. Name the source audio so the next person can find it: cinderlane_podcast_preroll_en_v1 and cinderlane_podcast_midroll_en_v1. When the trial window changes, open the sentence, generate, bump to v2, replace the clip. Leave the proof that is still true. That is the reason you did not re-book the host for the close.

If a network inserts ads dynamically, the job is the same file in a different folder. Hand them the standalone export and confirm the live slot spec on that host — length, loudness, channel — before you treat the render as inserted. We describe the drop because insertion UIs move. We are not inventing a control name we cannot see on a public help page.

A royalty-safe bed is a second pass, not this hop. If the episode still needs original audio that is not a ripped YouTube track, that workflow lives at How to add AI music to a podcast — ordinary site path. Do not upload a silent enclosure and then tap a host’s music library to “add the VO in-app.” That swaps you back onto someone else’s license and can mute the layer you paid for.

Listeners still deserve a plain-language note when the break is an ad — and, when it matters, when the voice is synthetic. Say the break is sponsored out loud. IAB’s January 2026 framework treats a generic stock narrator, where the speaker’s identity is immaterial, as standard narration; it treats a named-person clone making statements they never made as a disclosure case. Confirm the live text. If the voice could be taken as the host, you are in the clone how-to, not a Studio slider. If a network or host exposes an AI or synthetic-media control, use the live toggle. We describe the action because the label copy moves. Those disclosures are separate from the vendor license. You need both. Paid-feed terms can be stricter than a hobby RSS; read them before you publish.

Commercial rights, the enclosure, and the next cut

Read the live page. Murf meters voice generation in hours. Free lists no downloads and no commercial rights. Paid Studio plans are where the Export menu and commercial rights start. Confirm checkout. We do not print a commission rate. A 15–30 second host-read is a rounding error on the hour cap. The plan question is the license, not the meter. Sit on a paid plan before the file is the one a monetized feed serves.

If you later want the host’s likeness on the break, that is the clone how-to, not a reason to start this brief in Enterprise. If the remaining job is a 60–90s concept explainer, the Murf explainer page is that brief. If the remaining job is a taught step, the Murf course-lesson page is that brief. If the remaining job is a missed-call drop, the Murf sales-voicemail page is that brief. If the remaining job is a third-person announcer mid-roll, the Murf podcast-ad-voiceover page is that brief. If the remaining job is a 10–20 second open, the ElevenLabs podcast-intro page is that brief. If the remaining job is a bed, the Mubert podcast how-to is that brief. The voice-tool comparison lives on ElevenLabs vs Murf vs Synthesys. This page does not hop there. The only Try button here is Murf.
