Audio-native interaction intelligence

Every call says more than the words.

HeyTone reads how two voices move each other on a call, not just how each one sounds. From the audio alone, see the moment one voice shifts the other, the layer transcripts cannot reach.

Long before words, there was tone. Every voice still carries it: pitch, pace and silence, a record of what we feel but never say. The signal was always there, waiting to be read.

Says Yes, Means No

We flag every moment the words and the tone disagree. A polite "sounds good" in a flat, tense voice is exactly what a transcript hides.

FAQ

Questions, answered.

What does HeyTone do?

It reads how two voices move each other on a call, from the audio itself. Not just how each person sounds, but the moments one voice shifts the other: rapport building, tension spreading, a confident yes that is really a hesitant one. You get a structured read of what moved the call and what to do next.

How is this different from transcript tools?

Transcript tools only see the words. HeyTone reads the voice itself, how energy, hesitation and timing move between the two speakers, signals that never reach the transcript, then ties them back to what was said.

What do I need to give it?

Just an audio recording of the call. HeyTone handles the rest and returns one structured analysis you can read or pull into your own tools.

What is in the analysis?

A timeline of the call with speaker roles, an emotional read at each moment, the key moments such as objections, buying signals and friction, the outcome, and concrete recommendations.

What kind of calls does it work on?

It is built for one to one voice conversations like sales and customer calls. It handles real-world audio from cafes, cars, or speakerphone by isolating the voice before analysis, so noisy calls stay analyzable.

Is my audio kept private?

Audio is processed for your analysis only. We do not train on customer data, do not retain raw recordings beyond the analysis window, and do not link voices across calls. EU region available. Full DPA on request.

How do I get access?

Currently working with select voice platforms and call teams. Reach out and we'll run an analysis on your own calls.
