The Goal
To build a backend-powered pronunciation feedback system that analyzes a user’s spoken English audio, compares it to the expected text, and returns detailed phoneme-level feedback.
Sample Request
{ "text": "Hello there! It's nice to finally meet you.", "audio": "<base64-encoded WAV>" }Expected Response
{ "phrase": "Hello there...", "phonemes": [ {"phoneme": "h", "start": 0.12, "end": 0.18, "status": "correct"}, {"expected": ["e", "l"], "actual": ["æ"], "status": "wrong"}, {"expected": ["oʊ"], "status": "missing"}, ... ] }
