Descript Overdub Review: Voice Cloning Built Into a Text-Based Editor

⏱ 7 Reading Time

Descript Overdub clones a user’s voice from a short audio sample and generates new speech from typed text inside Descript’s text-based video and audio editor. Descript renamed the feature internally to Regenerate and AI Speech, but “Overdub” remains the name most creators search for.

What Is Descript Overdub?

Overdub is Descript’s AI voice cloning feature that lets a user type a script and generate audio in their own cloned voice, directly inside the same editor used for transcription and video editing. Descript built the original technology on Lyrebird AI, a company it acquired in 2019, and has since migrated voice generation onto licensed ElevenLabs models.

What Are Overdub’s Key Features?

Overdub’s feature set spans three functions: cloning a voice, generating new speech, and correcting existing recordings.

• Clone a voice from sample audio. Descript trains a custom voice model from a few minutes of recorded speech and requires a spoken consent statement before activation.
• Generate speech from typed text. Users write a script in Write mode, assign an AI Speaker, and Descript renders audio through the ElevenLabs Multilingual v2 model.
• Correct a flubbed word without re-recording. Regenerate replaces a single misspoken word or phrase by editing the transcript text, matching the surrounding vocal tone.
• Convert generated speech into editable audio. A generated AI voice clip converts into a Timeline audio layer, unlocking trims, crossfades, and effects that raw AI clips don’t support.
• Draw from a shared AI credit pool. Free includes 100 one-time AI credits; Hobbyist includes 400 AI credits per month; Creator includes 800; Business includes 1,500 (source: descript.com/pricing).
• Hit an audible cutoff at the credit limit. Exceeding the AI credit allocation plays a placeholder “jibber jabber” sound in place of the missing generated words instead of failing silently.
• Switch between two supported voice models. App Settings lets a user toggle AI models for different generation speed and language coverage needs.

How Much Does Descript Cost for Overdub Access?

Overdub requires at minimum the Hobbyist plan at $16 per month (billed annually) or $24 per month (billed monthly); the Free plan only grants 100 one-time AI credits for testing. All figures below come from Descript’s official pricing page, current as of July 2026.

AI credits get shared across every AI tool in the account — Studio Sound, Green Screen, Eye Contact, Underlord, and Overdub all draw from the same monthly pool. Descript sells additional credit top-ups on Creator and Business plans, and those top-ups expire 12 months after purchase.

What Are the Pros and Cons of Descript Overdub?

Overdub saves time by editing audio through text, but the September 2025 shift to a shared AI-credit system means heavy voice cloning use competes with every other AI feature in the account for the same monthly quota.

Pros:

• Clones a voice and generates new dialogue inside the same app used for transcription, captions, and video export — no round-tripping audio to a separate tool.
• Free plan includes 100 one-time AI credits, enough to test voice cloning before purchasing a subscription.
• Native-sounding AI speakers cover 14 languages: English, Spanish (ES), Spanish (LatAm), French, Italian, German, Portuguese (BR), Polish, Dutch, Swedish, Hindi, Turkish, Chinese, Japanese, and Korean.
• Corrects a single misspoken word through Regenerate instead of forcing a full re-record of a take.

Cons:

• AI credits are pooled across Studio Sound, Green Screen, Underlord, and Overdub, so a heavy voice-cloning month can exhaust the quota needed for other AI edits.
• Independent testing reports crashes and inconsistent output quality since the credit-metered system replaced the older flat-vocabulary model.
• Exceeding the credit allocation inserts audible “jibber jabber” placeholder audio rather than pausing generation cleanly.
• Descript exposes fewer manual tuning controls (no stability or clarity sliders) than dedicated voice-cloning platforms.

How Does Descript Overdub Compare to ElevenLabs?

ElevenLabs unlocks Professional Voice Cloning at $22 per month on its Creator plan and exposes more granular voice controls than Descript, while Descript bundles voice cloning into a full video and podcast editor starting at $16 per month.

Who Should Use Descript Overdub?

Overdub fits creators who already edit audio or video in Descript and want to fix flubbed lines or generate short voiceover segments without leaving the editor. Podcasters correcting a misspoken name mid-episode, YouTubers patching a narration line after final export, and course creators updating a single sentence in an existing lesson all use Overdub inside their normal editing pass. Solo indie developers building a voice-enabled app, and teams that need an API-first voice cloning integration with granular parameter control, fit ElevenLabs or Resemble AI better than Descript’s editor-bound feature.

What Are the Best Alternatives to Descript Overdub?

• ElevenLabs unlocks Professional Voice Cloning on its $22/month Creator plan and exposes stability and clarity controls that Descript’s simplified interface doesn’t offer. Read the full ElevenLabs Review.
• Murf AI restricts voice cloning to its Business plan at roughly $66–$99/month, but includes native PowerPoint and Canva integration that Descript lacks.
• Resemble AI bills per second of generated audio on a pay-as-you-go Flex plan starting at $0, targeting developers building voice agents and needing deepfake-detection watermarking.

Frequently Asked Questions

Is Descript Overdub still called “Overdub”?

Descript renamed the underlying features to Regenerate (word-level correction) and AI Speech / Custom Voice Clones (full script generation), though “Overdub” remains the commonly searched legacy name for both.

Does the Descript Free plan include Overdub?

Yes. The Free plan includes 100 one-time AI credits that cover limited voice cloning and generation before a paid plan becomes necessary.

What happens when Overdub runs out of AI credits?

Descript plays a “jibber jabber” placeholder sound in place of the missing generated words instead of stopping generation cleanly, based on independent testing of the credit-metered plans.

Which Descript plan unlocks unlimited voice cloning?

No current plan offers unlimited voice cloning; every tier, including Business at 1,500 AI credits per month, draws voice generation from a shared, capped AI credit pool.

Overdub costs nothing to sample on Descript’s Free plan, but sustained use of the feature — cloning a voice and generating full scripts on a repeating basis — requires at least the $16-per-month Hobbyist plan, and that plan’s 400 monthly AI credits get split across every other AI tool in the account, not reserved for voice cloning alone.
