# ElevenLabsSpeechToText - ComfyUI Built-in Node Documentation

> Complete documentation for the ElevenLabsSpeechToText node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ElevenLabs Speech to Text node transcribes audio files into text. It uses ElevenLabs' API to convert spoken words into a written transcript, supporting features like automatic language detection, identifying different speakers, and tagging non-speech sounds like music or laughter.

## Inputs

| Parameter                | Description                                                                                                                                                                                       | Data Type | Required | Range                                     |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------- |
| `audio`                  | Audio to transcribe.                                                                                                                                                                              | AUDIO     | Yes      | -                                         |
| `model`                  | Model to use for transcription. Selecting this model reveals additional parameters.                                                                                                               | COMBO     | Yes      | `"scribe_v2"`                             |
| `tag_audio_events`       | Annotate sounds like (laughter), (music), etc. in transcript. This parameter is revealed when the `"scribe_v2"` model is selected. (default: False)                                               | BOOLEAN   | No       | -                                         |
| `diarize`                | Annotate which speaker is talking. This parameter is revealed when the `"scribe_v2"` model is selected. (default: False)                                                                          | BOOLEAN   | No       | -                                         |
| `diarization_threshold`  | Speaker separation sensitivity. Lower values are more sensitive to speaker changes. This parameter is revealed when the `"scribe_v2"` model is selected and `diarize` is enabled. (default: 0.22) | FLOAT     | No       | 0.1 - 0.4                                 |
| `temperature`            | Randomness control. 0.0 uses model default. Higher values increase randomness. This parameter is revealed when the `"scribe_v2"` model is selected. (default: 0.0)                                | FLOAT     | No       | 0.0 - 2.0                                 |
| `timestamps_granularity` | Timing precision for transcript words. This parameter is revealed when the `"scribe_v2"` model is selected. (default: "word")                                                                     | COMBO     | No       | `"word"`<br />`"character"`<br />`"none"` |
| `language_code`          | ISO-639-1 or ISO-639-3 language code (e.g., 'en', 'es', 'fra'). Leave empty for automatic detection. (default: "")                                                                                | STRING    | No       | -                                         |
| `num_speakers`           | Maximum number of speakers to predict. Set to 0 for automatic detection. (default: 0)                                                                                                             | INT       | No       | 0 - 32                                    |
| `seed`                   | Seed for reproducibility (determinism not guaranteed). (default: 1)                                                                                                                               | INT       | No       | 0 - 2147483647                            |

**Note:** The `num_speakers` parameter cannot be set to a value greater than 0 when the `diarize` option is enabled. You must either disable `diarize` or set `num_speakers` to 0.
