Azure Speech Translator

This Python script uses Azure Cognitive Services to transcribe and translate audio files into different languages. It takes input audio files, transcribes them using the Azure Speech Service SDK, and translates the transcriptions into the desired output language using the Azure Translator Service SDK. The Translator Service SDK is currently in public preview, with GA date TBD.

Requirements

• Python 3.6 or higher
• Azure Cognitive Services Speech SDK
• Azure Speech Service
• Azure Translator Service

Installation

1. Install the required Python packages:

pip install azure-cognitiveservices-speech azure-ai-translation-text python-dotenv

2. Sign up for an Azure account and create a Speech Service and a Translator Service. Note the keys and endpoints for each service.

3. Create a .env file in the same directory as the script and add the following environment variables:

AZURE_SPEECH_KEY=<your_speech_service_key>
AZURE_SERVICE_REGION=<your_speech_service_region>
AZURE_TRANSLATOR_KEY=<your_translator_service_key>
AZURE_TRANSLATOR_ENDPOINT=<your_translator_service_endpoint>

Replace <your_speech_service_key>, <your_speech_service_region>, <your_translator_service_key>, and <your_translator_service_endpoint> with the appropriate values from your Azure account.

Usage

Run the script with the following command:

python azure_translator.py --in-lang <input_language> --out-lang <output_language> <input_audio_pattern> <output_file> [--transcription <transcription_output_file>]

• <input_language>: Input language (e.g., english, spanish, estonian, french, italian, german)
• <output_language>: Output language (e.g., english, spanish, estonian, french, italian, german)
• <input_audio_pattern>: Path to the input audio file(s), with support for wildcard patterns (e.g., ./*.wav)
• <output_file>: Path to the output file containing the translation
• <transcription_output_file> (optional): Path to the output file containing the transcription

Example:

python .\azure_translator.py --in-lang spanish --out-lang english '.\Spanish test.wav' .\translation.txt

This command will transcribe and translate the included test audio file from Spanish to English. The translation will be saved in translation.txt with the following output:

Processing audio file: .\Spanish test.wav
Transcribed text: Esta es una prueba del sistema de transmisión de emergencia. Solo es una prueba si esto fuera una emergencia real, estaría corriendo para salvar mi vida.
Translated text: This is a test of the emergency transmission system. It's just a test if this was a real emergency, I would be running for my life.
