This page is the lookup table for Voice Cloning: what the Instant and Professional tabs accept, what a clone costs in credits, when the charge is taken, and what you see when the workspace balance cannot cover it. What a credit is and the rates are on [Credits](/docs/developers/credits). ## Limits | Limit | Instant | Professional | | ------------------------ | -------------------------------------------------- | ------------------------------------ | | Audio | One clip of 10 to 30 seconds | 10 minutes to 3 hours in total | | Files | One. A new clip replaces the old one | Up to 20, 2 GB in total | | Clear speech | Not a separate limit | At least 20 minutes after cleanup | | Recording in the browser | Stops at 30 seconds | Stops at 30 minutes | | Code recording | 3 to 10 seconds | 3 to 10 seconds | | In progress | Ready in a few seconds | One professional voice per workspace | | Voices per workspace | 20. A professional voice in progress counts as one | Same | | Name | Up to 60 characters, unique in the workspace | Same | | Codes per user | 20 per 10 minutes | Same | | Code checks per user | 10 per 10 minutes | Same | | Who can clone | Anyone with the `clone.use` permission | Same | ## What a clone costs | Clone | Fee | Build or training | | ------------ | ----- | ------------------------------- | | Instant | $2.00 | 500 credits for the build | | Professional | $5.00 | 1,800 credits per training hour | The dollar fee is taken in credits at the rate of the credits that pay. On the rates in [Credits](/docs/developers/credits), the fee is: | Credits that pay | Instant, $2.00 | Professional, $5.00 | | -------------------------------------------- | -------------- | ------------------- | | Extra credits (28,571.43 per $1) | 57,143 | 142,857 | | Starter monthly and trial (31,578.95 per $1) | 63,158 | 157,895 | Other plans have other rates. The fee is rounded to a whole credit on its own. Every clone also pays for its checks, its transcription, its cleaning and its preview line: | Charge | Rate | | ------------------ | ------------------------------------------ | | Liveness check | 2 credits per second of the code recording | | Same-speaker check | 1 credit per second compared | | Speech to Text | 100 credits per minute | | Sound cleaning | 1,000 credits per minute | | Preview line | 1 credit per character | The checks, the transcription and the cleaning are charged per second. The credit lines of one clone, preview line included, are added up and rounded once to a whole credit. ## When you are charged | Moment | What happens | | --------------------------- | ---------------------------------------------------------------------------------------------- | | Instant, when you confirm | The whole price is charged before the voice is built, and refunded in full if the build fails. | | Professional, at the start | The price is charged for a 1 hour training estimate, fee included. | | Professional, training ends | Only the difference in training time is charged or refunded. | | A clone fails | The charge is refunded in full. | | You use the voice | Text to Speech costs the same as with any voice. | ## When the balance cannot cover a clone The page shows an estimate before you confirm: **This voice costs about N credits.** For Professional it reads **This voice costs about N credits with 1 hour of training. The final price is set when training ends.** If the workspace balance is lower than the estimate, the request is refused with **Insufficient subscription balance**. Add credits before you confirm. The ways to add credits are on [Credits, top-ups and rollover](/docs/account/credits-top-ups-rollover). If cloning has no published price, the page reads **Price not set yet. Voice cloning opens once its price is published.** Nothing is charged. Try again later. ## Using a cloned voice A cloned voice works in Text to Speech (the voice picker has a **Cloned** filter), on the Voices page under **Recorded by you**, in **Assets** on its **Voice Cloning** tab and in EchoReader. See [Generate speech](/docs/playground/generate-speech) and [Voice Library](/docs/playground/voice-library). It costs the same as any voice. It does not work in agents yet. ## Worked example An Instant clone from a 20 second sample with a 10 second code recording: | Line | Quantity and rate | Credits | | ---------------------- | ------------------------------ | ------- | | Speech to Text, code | 10 seconds at 100 per minute | 16.67 | | Liveness check | 10 seconds × 2 | 20 | | Same-speaker check | 10 + 20 = 30 seconds × 1 | 30 | | Sound cleaning, sample | 20 seconds at 1,000 per minute | 333.33 | | Speech to Text, sample | 20 seconds at 100 per minute | 33.33 | | Build | 1 voice | 500 | | Preview line | 1 per character of the line | P | | Fee | $2.00, taken in credits | F | The lines above P and F add up to 933.33 credits. Those lines and the P preview characters are added and rounded once to a whole credit. The fee is converted to credits and rounded on its own: F is 57,143 at the extra-credit rate, so the total is about 58,076 + P credits. The page shows the total before you confirm: **This voice costs about N credits.** A Professional clone from 45 minutes of audio with a 10 second code recording: | Line | Quantity and rate | Credits | | --------------------- | --------------------------------- | ------- | | Speech to Text, code | 10 seconds at 100 per minute | 16.67 | | Liveness check | 10 seconds × 2 | 20 | | Same-speaker check | 10 + 30 = 40 seconds × 1 | 40 | | Speech to Text, audio | 45 minutes at 100 per minute | 4,500 | | Sound cleaning, audio | 45 minutes at 1,000 per minute | 45,000 | | Training | 1 hour estimate at 1,800 per hour | 1,800 | | Preview line | 1 per character of the line | P | | Fee | $5.00, taken in credits | F | The lines above P and F add up to 51,376.67 credits. With the P preview characters they are rounded once. F is 142,857 at the extra-credit rate, so the total is about 194,234 + P credits. That is the 1 hour estimate. When training ends, only the difference in training time is charged or refunded. The audio alone costs 1,100 credits per minute. ## FAQ ### Can I see the price before I confirm? Yes. The page shows **This voice costs about N credits.** before the code step. See [Clone your voice](/docs/playground/clone-your-voice). ### Am I charged if a clone fails? No. A failed clone is refunded in full. ### Does a longer sample cost more? Yes. For Instant, the transcription, the cleaning and the same-speaker check are charged per second, so a longer sample adds to the total. For Professional, the same-speaker check compares the code recording with 30 seconds, so it does not grow. The transcription and the cleaning of all your audio do: 1,100 credits per minute. ## Related - [Clone your voice](/docs/playground/clone-your-voice): the Instant clone from 10 to 30 seconds. - [Train a professional voice](/docs/playground/train-a-professional-voice): a closer match from 10 minutes to 3 hours of audio. - [Record a good sample for cloning](/docs/playground/record-a-good-sample): how to get a clean recording. - [Credits](/docs/developers/credits): what a credit is and the rates. - [Credits, top-ups and rollover](/docs/account/credits-top-ups-rollover): add credits.
