Use the returned WebSocket url to connect to the WebSocket and start sending audio chunks. Use the returned id and the GET /v2/live/:id endpoint to obtain the status and results.
  • Security: Generate the WebSocket URL on your backend and keep your API key private. The init call returns a connectable URL and a session id that you can safely pass to web, iOS, or Android clients without exposing credentials in the app.
  • Lower infrastructure load: The secure URL is generated on your backend, the client can connect directly to Gladia’s WebSocket server without a pass-through on your side, saving your own resources.
  • Resilient reconnection and session continuity: If the WebSocket disconnects (which can happen on unreliable networks), the session created by the init call lets the client reconnect without losing context. Traditional flows that open a socket first typically force a brand‑new session on disconnect, dropping in‑progress state.

x-gladia-key
string
header
required

Your personal Gladia API key

Query Parameters

​
region
enum<string>

The region used to process the audio.

Available options:
us-west,
eu-west

Body

application/json
​
encoding
enum<string>
default:wav/pcm

The encoding format of the audio stream. Supported formats:

  • PCM: 8, 16, 24, and 32 bits
  • A-law: 8 bits
  • μ-law: 8 bits

Note: No need to add WAV headers to raw audio as the API supports both formats.

Available options:
wav/pcm,
wav/alaw,
wav/ulaw
​
bit_depth
enum<number>
default:16

The bit depth of the audio stream

Available options:
8,
16,
24,
32
​
sample_rate
enum<number>
default:16000

The sample rate of the audio stream

Available options:
8000,
16000,
32000,
44100,
48000
​
channels
integer
default:1

The number of channels of the audio stream

Required range: 1 <= x <= 8
​
custom_metadata
object

Custom metadata you can attach to this live transcription

Example:
{ "user": "John Doe" }
​
model
enum<string>
default:solaria-1

The model used to process the audio. "solaria-1" is used by default.

Available options:
solaria-1
​
endpointing
number
default:0.05

The endpointing duration in seconds. Endpointing is the duration of silence which will cause an utterance to be considered as finished

Required range: 0.01 <= x <= 10
​
maximum_duration_without_endpointing
number
default:5

The maximum duration in seconds without endpointing. If endpointing is not detected after this duration, current utterance will be considered as finished

Required range: 5 <= x <= 60
​
language_config
object

Specify the language configuration

​
pre_processing
object

Specify the pre-processing configuration

​
realtime_processing
object

Specify the realtime processing configuration

​
post_processing
object

Specify the post-processing configuration

​
messages_config
object

Specify the websocket messages configuration

​
callback
boolean
default:false

If true, messages will be sent to configured url.

​
callback_config
object

Specify the callback configuration

Response

The live job has been initiated

​
id
string<uuid>
required

Id of the job

Example:

"45463597-20b7-4af7-b3b3-f5fb778203ab"

​
created_at
string<date-time>
required

Creation date

Example:

"2023-12-28T09:04:17.210Z"

​
url
string<uri>
required
