# FishAudioSpeechToText - ComfyUI Built-in Node Documentation

> This node transcribes audio into text using the Fish Audio speech-to-text service.

This node transcribes audio into text using the Fish Audio speech-to-text service. It automatically detects the language of the audio and can optionally return word-level timestamped segments as JSON.

## Inputs

| Parameter            | Description                                                                                                      | Data Type | Required | Range                                                                         |
| -------------------- | ---------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------------------------------------- |
| `audio`              | Audio to transcribe.                                                                                             | AUDIO     | Yes      | —                                                                             |
| `language`           | ISO 639-1 language hint (e.g. 'en', 'zh'). The language is auto-detected regardless. Default: "" (empty string). | STRING    | No       | Any ISO 639-1 language code, e.g. `en`, `zh`; empty string for auto-detection |
| `precise_timestamps` | Return word-level timestamped segments. Default: false.                                                          | BOOLEAN   | No       | true or false                                                                 |

Note: The `language` parameter is only a hint — the language is always auto-detected from the audio. When `precise_timestamps` is false (the default), word-level timestamps are not returned; when true, the output segments include word-level timestamps.

## Outputs

| Output Name     | Description                                                                                                             | Data Type |

| `text`          | The transcribed text.                                                                                                   | STRING    |
| `language_code` | The ISO 639-1 language code detected for the audio.                                                                     | STRING    |
| `segments_json` | JSON string containing the transcription segments. Includes word-level timestamps when `precise_timestamps` is enabled. | STRING    |
