# Get TTS Generation

> Retrieve a single stored text-to-speech generation.

## Headers

**authorization** `string` *required*

Your API key for authentication.

## Path Parameters

**id** `string` *required*

The ID of the generation to retrieve.

## Query Parameters

**format** `string`

Pass `audio` to receive the raw WAV binary instead of the metadata JSON.

## Response

Without `?format=audio`, returns the generation metadata:

**id** `string`

Unique identifier for the generation.

**org\_id** `string`

The organization that created the generation.

**user\_id** `string`

The user that created the generation.

**text** `string`

The text that was synthesized.

**voice\_id** `string`

The voice used for synthesis.

**output\_format** `string`

The audio format of the generation (e.g. `pcm_44100`).

**audio\_data** `string`

Base64-encoded audio data. Only present in the JSON response (not when using `?format=audio`).

**latency\_ms** `number`

Time in milliseconds from request to first audio.

**cost** `number`

Cost in USD for this generation.

**created\_at** `string`

ISO 8601 timestamp of when the generation was created.

With `?format=audio`, returns a raw WAV audio binary (same as the original `POST /v1/speak` response).
