# ElevenLabsSpeechToText - ComfyUI Built-in Node Documentation

> The ElevenLabs Speech to Text node transcribes audio into text using the ElevenLabs API.

The ElevenLabs Speech to Text node transcribes audio into text using the ElevenLabs API. It supports automatic language detection, speaker diarization (identifying different speakers), and audio event tagging (annotating sounds like laughter or music in the transcript).

## Inputs

### Common Inputs

| Parameter       | Description                                                                                                        | Data Type      | Required | Range          |
| --------------- | ------------------------------------------------------------------------------------------------------------------ | -------------- | -------- | -------------- |
| `model`         | Model to use for transcription. Selecting this model reveals additional parameters.                                | DYNAMIC\_COMBO | Yes      | `"scribe_v2"`  |
| `audio`         | Audio to transcribe.                                                                                               | AUDIO          | Yes      | -              |
| `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 |

### Scribe v2 Inputs

These parameters are shown when the `"scribe_v2"` model is selected.

| Parameter                | Description                                                                                                                              | Data Type | Required | Range                                     |
| ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------- |
| `tag_audio_events`       | Annotate sounds like (laughter), (music), etc. in transcript. (default: False)                                                           | BOOLEAN   | No       | -                                         |
| `diarize`                | Annotate which speaker is talking. (default: False)                                                                                      | BOOLEAN   | No       | -                                         |
| `diarization_threshold`  | Speaker separation sensitivity. Lower values are more sensitive to speaker changes. Only used when `diarize` is enabled. (default: 0.22) | FLOAT     | No       | 0.1 - 0.4                                 |
| `temperature`            | Randomness control. 0.0 uses model default. Higher values increase randomness. (default: 0.0)                                            | FLOAT     | No       | 0.0 - 2.0                                 |
| `timestamps_granularity` | Timing precision for transcript words. (default: "word")                                                                                 | COMBO     | No       | `"word"`<br />`"character"`<br />`"none"` |

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