## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `seed` | number | null | no |  |
| `text` | string | yes | The text that will get converted into speech. |
| `model_id` | string | no | Identifier of the model that will be used, you can query them using GET /v1/models. The model needs to have support for text to speech, you can check this using |

| `next_text` | string | null | no |  |
| `language_code` | string | null | no |  |
| `output_format` | string | no | Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. MP3 w |
| `previous_text` | string | null | no |  |
| `enable_logging` | boolean | no | When enable_logging is set to false zero retention mode will be used for the request. This will mean history features are unavailable for this request, includin |

## Why text_to_speech_stream_with_timestamps is rated Low

Even though text_to_speech_stream_with_timestamps only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: High parameter count (17 properties)

## Use case

AI agents call text_to_speech_stream_with_timestamps to retrieve information from Elevenlabs without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
