What the analyzer returns
As you speak, the demo chunks your audio and sends it to POST /v1/audio/analysis, which returns the transcript plus calibrated multilabel scores. Emotion labels (15): happy, excited, hopeful, sad, worried, angry, frustrated, disappointed, scared, disgusted, surprised, embarrassed, proud, relieved, neutral. Speaking-style labels (16): energetic, passionate, irritated, warm, playful, sarcastic, deadpan, hesitant, confident, sincere, skeptical, tired, formal, casual, impatient, distracted.
Scores are calibrated on held-out audio, so a label is only attached when it crosses its measured threshold. Outputs are acoustic annotations of how speech sounds — not claims about a speaker’s inner state. See capabilities and scope.
FAQ
- Is this voice emotion analyzer free?
- Yes. The demo on this page runs against the live oruk Speech API at no cost and with no account. For your own applications, new API accounts include $5 in trial credit.
- Is my voice recording stored?
- No. Audio is captured in your browser, sent to the API over TLS, analyzed, and discarded once the response is returned. Nothing is retained or used for training.
- How does the analyzer detect emotion from voice?
- An acoustic model scores 15 emotion labels and 16 speaking-style labels directly from the audio signal — pitch, pace, energy, timbre — with thresholds calibrated on held-out audio. Labels describe how the speech sounds, not what the speaker inwardly feels.
- What languages does it support?
- The transcription and labels are built for English audio. Other languages may return output, but accuracy is not evaluated or supported in API v1.
- Can I use this in my own product?
- Yes — the demo calls the same POST /v1/audio/analysis endpoint you would integrate: one REST request with an audio file returns the transcript, emotion labels, style labels, and time-local segments.
