Real-Time Speech Translator

Objectives

• Capture live microphone input and stream it for transcription
• Transcribe speech in the source language using Whisper
• Translate the transcript to the target language using an LLM or translation API
• Speak the translation aloud using a TTS voice in the target language
• Minimize end-to-end latency for near-real-time conversation flow

Hints

• Process audio in short overlapping chunks for lower latency
• Use streaming APIs where available to reduce wait times
• Display both the original transcript and translation side by side
