Accepts `multipart/form-data` - send `ref_audio` as a file upload and all other parameters as form fields. **Two ways to clone:** 1. **Reference clip** - upload `ref_audio` (optionally with its transcript in `ref_text`). 2. **Saved voice** - pass a `voice_id` from your voice library; the stored reference audio and transcript are reused. **Base URL:** `https://api.sarvam.ai`. **Auth:** send your key in the `api-subscription-key` header (recommended); `Authorization: Bearer ` is also accepted. The cloned voice is cross-lingual: the reference clip's language does not need to match `language_code`. The model preserves the speaker's timbre and identity while applying the phonetics and prosody of the target language. **Billing:** charged per character of `text` against the `text_to_speech_voice_cloning` API. See the [pricing page](https://docs.sarvam.ai/api/getting-started/pricing). Reference: https://docs.sarvam.ai/api-reference/voice-cloning/clone ## Authentication - `api-subscription-key` header (required) — API Key authentication via header ## Request ### Body (multipart/form-data) This endpoint expects a multipart form containing an optional file. - `ref_audio` (file, optional) — Reference audio file for voice cloning. Supported formats: WAV, MP3, FLAC, OPUS, AAC, MULAW, ALAW, LINEAR16. WAV is recommended for best quality and fastest decoding. Limits: max file size 10 MB, max duration 30 seconds. Recommended duration is 10-15 seconds, single speaker, minimal background noise. Either `ref_audio` or `voice_id` is required. Sending both returns a 400 error. - `voice_id` (string, optional) — Cloned voice ID (`svc-{uuid}`) from your voice library, created via the Content Studio Voice Library. When provided, the reference audio stored for that voice is used and `ref_audio` is not needed. Requires your API key to be bound to an organization. Sending both `ref_audio` and `voice_id` returns a 400 error. - `text` (string, required) — Text to synthesize in the cloned voice. Native scripts and code-mixed text are supported. Maximum 1000 characters; longer text is rejected with a 400. Split longer input client-side and synthesize it in parts. - `language_code` (enum, required) — BCP-47 language code for the synthesized output. The cloned voice can speak any supported language, regardless of the reference clip's language (cross-lingual cloning). **Available Options:** - `as-IN`: Assamese - `bn-IN`: Bengali - `en-IN`: English (Indian) - `gu-IN`: Gujarati - `hi-IN`: Hindi - `kn-IN`: Kannada - `ml-IN`: Malayalam - `mr-IN`: Marathi - `od-IN`: Odia - `pa-IN`: Punjabi - `ta-IN`: Tamil - `te-IN`: Telugu - `pace` (double, optional) — Speech speed multiplier. `1.0` is natural speed; `0.5` to `2.0` is accepted. Speed is adjusted without changing pitch. Mutually exclusive with `max_audio_duration` - sending both returns a 400 error. - `ref_text` (string, optional) — Transcript of the reference audio. Optional: when omitted with a `ref_audio` upload, the API transcribes the reference clip automatically. Providing the actual transcript improves fidelity, especially for cross-lingual cloning. Maximum length is 500 characters. When using `voice_id`, the stored reference transcript is used unless you override it here. - `output_audio_codec` (enum, optional) — Audio codec for the output audio. Default is `wav`. - `wav`: Uncompressed. Best quality for downstream processing. - `mp3`: Smaller file size; suitable for web playback. - `flac`: Lossless compression. - `opus`: Low-bitrate codec ideal for streaming. When `speech_sample_rate` is explicitly set with `opus`, it must be one of 8000, 16000, 24000 or 48000 Hz; when omitted, opus output is returned at the native 24000 Hz. - `aac`: Common in mobile and broadcast. - `linear16`: Raw 16-bit PCM. - `mulaw` / `alaw`: 8-bit telephony codecs for IVR pipelines. - `speech_sample_rate` (enum, optional) — Output sample rate in Hz. Supported values are 8000, 16000, 22050, 24000, 32000, 44100, 48000. If omitted, the API returns 24000 Hz. This is a service-side default: the output is resampled to it, so it does not change with the generating model. Set it to match your downstream pipeline: 8000 for telephony/IVR, 16000 for voice agents, 24000 for web playback, 44100/48000 for broadcast. - `enable_qc` (boolean, optional) — Enable quality control: ASR transcription of the generated audio, character error rate (CER) scoring against the input text, and prompt-leak detection with bounded regeneration. Applies to single-chunk (short) generations; long text that is split into sentence chunks is generated without QC. Recommended for production use; disable only when you need the lowest latency or run your own downstream verification. - `enable_cached_responses` (boolean, optional) — Enable response caching. Coming soon - accepted for forward compatibility, currently ignored. - `enable_vad` (boolean, optional) — Enable VAD-based silence trimming of the generated audio. Default is `true`. Applies to single-chunk (short) generations; long text that is split into sentence chunks is returned untrimmed. - `enable_text_normalization` (boolean, optional) — Enable pre-TTS text normalization: numbers, currencies and dates are converted to their spoken form before synthesis (e.g. `9840950950` becomes the spoken digit sequence). Defaults to the server-side setting. Supported for all 12 languages accepted by `language_code`; any other code passes through unchanged. - `min_audio_duration` (double, optional) — Minimum output audio duration in seconds. If the generated audio is shorter, it is padded with silence. - `max_audio_duration` (double, optional) — Maximum output audio duration in seconds. If the generated audio is longer, it is time-stretched to fit. Must be >= `min_audio_duration`. Silently floored to the reference clip's duration when the clip is longer. Mutually exclusive with `pace` - sending both returns a 400 error. - `ref_audio_duration` (double, optional) — Override for the reference audio duration in seconds. Useful for dubbing/sync scenarios where the model should treat the reference as a specific length. ## Response ### 200 Successful Response - `audio` (string, required) — Base64-encoded output audio in the requested codec. - `request_id` (string, required) — Unique request identifier for debugging and support. - `audio_duration` (double, optional, nullable) — Duration of the generated audio in seconds. ## Errors ### 400 Bad Request Error Bad Request.
