API README
Qwen 3 TTS - Text to Speech [0.6B]
Qwen 3 TTS 0.6B, the open-weights Qwen speech model: text to speech in 10 languages with nine preset voices, or a cloned voice from a speaker-embedding file. The 0.6B model is the faster, cheaper size.
Fields
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string, required | — | Text to speak. |
text | string | — | Alias of prompt; if both are sent, text is used. |
top_p | number 0–1 | 1 | Sampling setting. |
subtalker_top_p | number 0–1 | 1 | Sub-model sampling setting. |
voice | Vivian / Serena / Uncle_Fu / Dylan / Eric / Ryan / Aiden / Ono_Anna / Sohee | — | Preset voice; ignored when a speaker embedding is supplied. |
repetition_penalty | number | 1.05 | Reduces repeated sounds. |
subtalker_top_k | integer | 50 | Sub-model sampling setting. |
top_k | integer | 50 | Sampling setting; leave at default unless delivery is unstable. |
reference_text | string | — | Transcript used when the embedding was created; improves cloned-voice quality. |
temperature | number 0–1 | 0.9 | Higher values give more varied delivery. |
max_new_tokens | integer 1–8192 | 200 | Caps the generated audio length; raise it for long text. |
language | Auto / English / Chinese / Spanish / French / German / Italian / Japanese / Korean / Portuguese / Russian | Auto | Spoken language; Auto detects it. |
subtalker_dosample | boolean | true | Sampling switch for the acoustic sub-model. |
subtalker_temperature | number 0–1 | 0.9 | Sub-model temperature. |
speaker_voice_embedding_file_url | string | — | Optional cloned-voice embedding (safetensors) to use instead of a preset voice. |
Billing
$0.07 per 1,000 characters of input text, billed per character.
| Text | Price |
|---|---|
| 100 characters | $0.007 |
| 1,000 characters | $0.07 |
| 5,000 characters | $0.35 |
Failed runs are not charged.
Prompting
- Use punctuation to control pauses; break long passages into paragraphs.
- Pick a voice whose primary language matches the text.
Limits
max_new_tokens(default 200) caps the audio length; long text needs a higher value.
