Example use cases
Voice coaching pitch feedback
“Take this audio clip of my practice speech and analyze the pitch and prosody — I need to know where my intonation rises and falls and whether my stress patterns sound natural.”
Emotion detection from speech
“Analyze the prosody and pitch features in this speech recording to help me understand the emotional tone — look for variations in pitch contour and rhythm that might indicate stress or excitement.”
Language learning pronunciation check
“I have a learner's spoken sentence recorded here — can you analyze the pitch and prosody to check if the intonation pattern matches native speaker norms?”
Technical details
Endpoint
POSThttps://api.m2mcent.com/prosody-pitch-analyzer-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need automated, per-call prosody and pitch extraction from speech data without building a local speech analysis pipeline. Best for agents that need acoustic intonation features programmatically as part of a voice quality, emotion, or linguistics workflow.
Side effects
- Invalid or malformed input data returns an error response
- Empty or missing data field causes processing failure
- Unsupported audio format or encoding may result in extraction errors
- Very short or silent audio clips may yield sparse or empty pitch metrics
- Network timeout for large audio payloads
