Audio

Quote Voice Changer

Get a price quote for converting a source recording of a given length.

Voice Changer is billed off the length of the source recording, rounded up to the next whole minute. This endpoint prices the length you declare, so the result is an estimate: the amount actually charged is computed from the length Venice measures server-side when the recording is queued. Where the two round to the same minute, the prices are identical — /audio/voice-changer/queue returns the measured duration_seconds so the estimate can be reconciled.

The whole-minute tiers are also published directly as pricing.durations in /models.

Use this endpoint before /audio/voice-changer/queue to estimate the USD cost of converting a source recording of a given length. Voice Changer is billed from the source duration, rounded up to the next whole minute. The queue response returns the measured duration_seconds so you can reconcile the estimate. Voice-changer models are not accepted on /audio/quote.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

model

string

required

The voice-changer model to price. Models that are not voice changers are not supported here; use /api/v1/audio/quote instead.

Example:

"elevenlabs-voice-changer"

duration_seconds

required

Length of the source recording in seconds. Voice Changer preserves timing, so the source length is the billable quantity, priced in whole-minute tiers. This is an estimate: the charge is computed from the length Venice measures server-side when the recording is queued. The per-model maximum is published as max_source_audio_duration_seconds in /models.

Required range: x > 0

Example:

60

Response

Estimated price for a conversion of the given source length

quote

number

required

Estimated price in USD for converting a recording of the given length.

Example:

0.35

duration_seconds

number

required

The source length this quote was computed for.

Example:

60
