Gladia Python SDK

A Python SDK for the Gladia API.

Requirements

You need Python 3.10+ for this package.

Installation

pip install gladiaio-sdk

# or with uv

uv add gladiaio-sdk

Usage

Import GladiaClient and create an instance.

Provide an API key with api_key or the GLADIA_API_KEY environment variable. Get your API key in under a minute.

You can also set GLADIA_API_URL. For live sessions, GLADIA_REGION (eu-west / us-west) is passed only on session creation (POST /v2/live).

Sync client

from gladiaio_sdk import GladiaClient

gladia_client = GladiaClient(api_key="your-api-key")

Pre-recorded transcription

transcribe() accepts a path, Path, binary file object, or http(s) URL. It uploads when needed, then polls until the job completes.

from gladiaio_sdk import GladiaClient

gladia_client = GladiaClient(api_key="your-api-key")

transcription = gladia_client.prerecorded().transcribe(
    "audio.mp3",
    {
        "language_config": {
            "languages": ["en"],
        },
    },
)

print(transcription.result.transcription.full_transcript)

See all the supported languages here!

Pass the options as the second argument to enable all the features from Audio intelligence — diarization, translation, PII redaction, and more.

Async pre-recorded

Use prerecorded_async() and await the same methods. Options match the sync API.

import asyncio

from gladiaio_sdk import GladiaClient


async def main() -> None:
    gladia_client = GladiaClient(api_key="your-api-key")

    transcription = await gladia_client.prerecorded_async().transcribe(
        "audio.mp3",
        {
            "language_config": {
                "languages": ["en"],
            },
        },
    )

    print(transcription.result.transcription.full_transcript)


asyncio.run(main())

Live transcription

Get a live client from your GladiaClient:

live_client = gladia_client.live()

Async version:

live_client = gladia_client.live_async()

from gladiaio_sdk import (
    LiveV2EndedMessage,
    LiveV2InitRequest,
    LiveV2InitResponse,
    LiveV2LanguageConfig,
    LiveV2MessagesConfig,
    LiveV2WebSocketMessage,
)

live_session = live_client.start_session(
    LiveV2InitRequest(
        model="solaria-1",
        encoding="wav/pcm",
        sample_rate=16000,
        bit_depth=16,
        channels=1,
        language_config=LiveV2LanguageConfig(
            languages=["en"],
        ),
        messages_config=LiveV2MessagesConfig(
            receive_partial_transcripts=True,
        ),
    )
)


@live_session.on("message")
def on_message(message: LiveV2WebSocketMessage):
    if message.type == "transcript":
        print(f"{'F' if message.data.is_final else 'P'} | {message.data.utterance.text.strip()}")


@live_session.once("started")
def on_started(response: LiveV2InitResponse):
    print(f"Session {response.id} started")


@live_session.on("error")
def on_error(error: Exception):
    print(f"An error occurred during live session: {error}")


@live_session.once("ended")
def on_ended(ended: LiveV2EndedMessage):
    print(f"Session {live_session.session_id} ended")


live_session.send_audio(audio_bytes)
live_session.stop_recording()

Use LiveV2InitRequest fields for realtime/post-processing options — see Live STT features and the live init API.

Async live

Same session API; use live_async() and run under asyncio.run or your app loop:

import asyncio

from gladiaio_sdk import (
    GladiaClient,
    LiveV2EndedMessage,
    LiveV2InitRequest,
    LiveV2InitResponse,
    LiveV2LanguageConfig,
    LiveV2MessagesConfig,
    LiveV2WebSocketMessage,
)


async def main() -> None:
    gladia_client = GladiaClient(api_key="your-api-key")
    live_client = gladia_client.live_async()
    session_done = asyncio.Event()

    live_session = live_client.start_session(
        LiveV2InitRequest(
            model="solaria-1",
            encoding="wav/pcm",
            sample_rate=16000,
            bit_depth=16,
            channels=1,
            language_config=LiveV2LanguageConfig(languages=["en"]),
            messages_config=LiveV2MessagesConfig(receive_partial_transcripts=True),
        )
    )

    @live_session.on("message")
    def on_message(message: LiveV2WebSocketMessage):
        if message.type == "transcript":
            print(f"{'F' if message.data.is_final else 'P'} | {message.data.utterance.text.strip()}")

    @live_session.once("started")
    def on_started(response: LiveV2InitResponse):
        print(f"Session {response.id} started")

    @live_session.on("error")
    def on_error(error: Exception):
        print(f"An error occurred during live session: {error}")
        session_done.set()

    @live_session.once("ended")
    def on_ended(ended: LiveV2EndedMessage):
        print(f"Session {live_session.session_id} ended")
        session_done.set()

    live_session.send_audio(audio_bytes)
    live_session.stop_recording()

    await session_done.wait()


asyncio.run(main())

When you need the session id from an async session: await live_session.get_session_id(). For a sync session, use live_session.session_id after started.
