Voice + WhatsApp · 118 languages · 30 voices
Conversations that hear how it was said, not just what.
A rushed voice at 9pm. The same question asked twice. A long pause before the real reason. Halloo answers on the phone and on WhatsApp with the sound in the room intact — and knows when to stop talking and get a person.
What it hears
The audio reaches the model. Nothing is flattened into text first.
Most voice agents transcribe you, answer the transcript, and read the answer back — so the pace, the sigh, the third time you have explained it are thrown away at the first step. Halloo runs speech-to-speech. What you sound like is part of what it is answering.
- Register
- Short with someone in a hurry, slower with someone lost. It never names your mood back at you.
- Interruption
- Say one word and the audio stops — and it knows your speakerphone echo from you talking.
- Pace
- It starts calm. Energy is something it lifts to match you, never the first thing you hear.
- Honesty
- Asked if it is an AI, it answers in one clause and moves on. Never a denial.
And a state can change what happens next: a complaint goes to a person, someone busy gets offered a time instead of a pitch. You draw that route once and it holds on the phone and in chat, because it is the same conversation either way.
