Fish Audio JavaScript SDK for RunAPI

Install @runapi.ai/fish-audio and create a FishAudioClient.

const created = await client.createVoice.run({ name: 'Narrator', source_audio_url: 'https://cdn.runapi.ai/public/samples/voice.mp3' });
const voice = await client.getVoice.run({ voice_id: created.voice.voice_id });
if (voice.voice.state !== 'trained') throw new Error(`Voice is ${voice.voice.state}`);
const result = await client.textToSpeech.run({ model: 's2.1-pro', text: 'Hello [excited]', voice_id: created.voice.voice_id, output_format: 'wav', sample_rate_hz: 44100 });

Pass optional references entries with base64-encoded raw audio bytes and exact transcripts for request-scoped voice matching.

Use listVoices and getVoice to inspect account-owned voice resources. Only trained voices can be submitted for speech generation; a returned voice_id is a best-effort reference and may stop working later. Update, delete, revoke, or voice-library management methods are not provided; voice retention is not promised.

The output defaults to MP3. Select WAV with output_format; bitrate_kbps applies only to MP3.
