Installation

1. Clone the repository: git clone https://github.com/folubebe/gemini_realtime_speech_to_text.git cd gemini_realtime_speech_to_text

2. Install dependencies: pip install -r requirements.txt

3. Create an API key from https://aistudio.google.com/apikey

Set the API key as an environment variable: set GOOGLE_API_KEY=your-api-key-here # Replace with your actual API key.

Alternatively, create a .env file in the project root with: GOOGLE_API_KEY=your-api-key-here # Replace with your actual API key.

Usage

Run the script: python speech_to_text.py

Follow the prompts to select your input device. The script will start recording audio in 5-second chunks, process them, and display translations in real-time.

You can modify the following parameters in the script:

• CHUNK_DURATION_SEC = 5: Duration in seconds for each audio processing chunk
• TARGET_LANGUAGE = "English": The desired output language for translation
• SOURCE_LANGUAGE = "auto": Source language detection (set to specific language to override auto-detection)

Press Ctrl+C to stop the recording. Transcriptions will be saved to translation_output.txt.
