TTS Voices
Every speech request names a voice by its voice_id. Shisa offers a catalogue of natural Japanese and English voices, each with its own language coverage, gender, supported audio formats, sample rates, and streaming capability. Query the catalogue programmatically so your application always uses an up-to-date list.
List available voices
GET https://api.shisa.ai/tts/voices
This endpoint returns a JSON array of voice objects. Authenticate with the same bearer token you use for speech generation:
curl -s -X GET "https://api.shisa.ai/tts/voices" \
-H "Authorization: Bearer YOUR_API_KEY" | jq .
Voice object fields
Each entry in the array is a voice object:
| Field | Type | Description |
|---|---|---|
id | string (uuid) | UUID to use as voice_id in requests. |
description | string | Human-readable voice description. |
language | string | Supported language(s). |
gender | string | Voice gender (Male, Female, Neutral). |
formats | array | Supported output audio formats. |
sample_rates | array | Supported output sample rates in Hz. |
streaming | boolean | Whether the voice supports real-time streaming. |
Example response:

{
"id": "e3362c0a-7677-4cd8-b122-91fb093305c9",
"description": "Young male Japanese voice...",
"language": "Japanese & English",
"gender": "Male",
"formats": ["mp3", "ogg", "pcm"],
"sample_rates": [8000, 16000, 22050, 24000, 32000, 44100, 48000],
"streaming": true
}
]
note
A voice only accepts the format values listed in its formats array and the sample_rate values listed in its sample_rates array, and stream: true only works when streaming is true. Requesting an unsupported format returns a 400 error.
