Project description

Deepgram Python SDK

Contributor Covenant

This SDK is under active development; feel free to provide feedback via GitHub issues and suggest new features.

Official Python SDK for Deepgram's automated speech recognition APIs.

To access the API you will need a Deepgram account. Sign up for free at console.deepgram.com.

You can learn more about the full Deepgram API at developers.deepgram.com.

Getting Started

pip install deepgram-sdk
from deepgram import Deepgram

dg_client = Deepgram(YOUR_API_KEY)
# or, fully specify for an alternate endpoint
dg_client = Deepgram({
    'api_key': YOUR_API_KEY,
    'api_url': YOUR_API_URL
})

Usage

Basic transcription can be done like so:

Batch processing

from deepgram import Deepgram
import asyncio, json

DEEPGRAM_API_KEY = 'YOUR_API_KEY'
PATH_TO_FILE = 'some/file.wav'

async def main():
    # Initializes the Deepgram SDK
    dg_client = Deepgram(DEEPGRAM_API_KEY)
    # Open the audio file
    with open(PATH_TO_FILE, 'rb') as audio:
        # ...or replace mimetype as appropriate
        source = {'buffer': audio, 'mimetype': 'audio/wav'}
        response = await dg_client.transcription.prerecorded(source, {'punctuate': True})
        print(json.dumps(response, indent=4))

asyncio.run(main())

"Fake" streaming processing:

from deepgram import Deepgram
import asyncio, json

DEEPGRAM_API_KEY = 'YOUR_API_KEY'
PATH_TO_FILE = 'some/file.wav'

async def main():
    # Initializes the Deepgram SDK
    dg_client = Deepgram(DEEPGRAM_API_KEY)
    # Creates a websocket connection to Deepgram
    try:
        socket = await dg_client.transcription.live({'punctuate': True})
    except Exception as e:
        print(f'Could not open socket: {e}')
        return
    # Handle sending audio to the socket
    async def process_audio(connection):
        # Open the file
        with open(PATH_TO_FILE, 'rb') as audio:
            # Chunk up the audio to send
            CHUNK_SIZE_BYTES = 8192
            CHUNK_RATE_SEC = 0.001
            chunk = audio.read(CHUNK_SIZE_BYTES)
            while chunk:
                connection.send(chunk)
                await asyncio.sleep(CHUNK_RATE_SEC)
                chunk = audio.read(CHUNK_SIZE_BYTES)
        # Indicate that we've finished sending data
        await connection.finish()

    # Listen for the connection to close
    socket.register_handler(socket.event.CLOSE, lambda c: print(f'Connection closed with code {c}.'))
    # Print incoming transcription objects
    socket.register_handler(socket.event.TRANSCRIPT_RECEIVED, print)

    # Send the audio to the socket
    await process_audio(socket)

asyncio.run(main())

Parameters

Query parameters like punctuate are added as part of the TranscriptionOptions dict in the .prerecorded/.live transcription call. Multiple query parameters can be added similarly, and any dict will do - the types are provided for reference/convenience.

response = await dg_client.transcription.prerecorded(source, {'punctuate': True, 'keywords': ['first:5', 'second']})

Depending on your preference, you can also add parameters as named arguments, instead.

response = await dg_client.transcription.prerecorded(source, punctuate=True, keywords=['first:5', 'second'])
