Code Overview

get_language_code(language_name)

• Maps common language names to their respective language codes.

• Returns the language code for use in speech recognition and translation APIs.

transcribe_and_translate_realtime(source_language, target_language)

• Uses the speech_recognition library to capture speech from a microphone.

• Transcribes the speech into text using Google Web Speech API.

• Translates the transcribed text to the target language using Google Translate.

• Continuously listens for speech until interrupted.

Error Handling

• Unknown Speech: If the Google Web Speech API cannot understand the input, the application will notify the user.

• API Errors: If there's an issue with the speech recognition API, an error message will be displayed.

Future Improvements

• Add support for custom target languages specified by the user.

• Improve error handling for network or API issues.

• Allow dynamic adjustment of microphone sensitivity.
