AI voice agents that hold real business conversations.
It hears the person, works out what they said, decides what to say next, and replies in a natural voice — in about the time a human would take. Veytrix runs these at volume and returns a transcript, a summary and a rating for every call.
Four systems, one latency budget
Every conversational turn runs all four in sequence. The quality of the call depends on all four being fast — and on the handoffs between them.
- TelephonyPlaces the call and streams audio both ways over the phone network.
- Speech-to-textTranscribes live, deciding when the caller has finished a sentence rather than just paused to think.
- Language modelReads the conversation so far plus your instructions, and decides the next reply.
- Text-to-speechSpeaks the reply in a natural voice, and stops immediately if the person interrupts.
~1.5 seconds from the moment they stop speaking to the moment they hear a reply.
The hard part is not any single step — it is the handoffs. If turn-detection is too eager the agent talks over people; too slow and every reply feels laggy. That tuning is the difference between a demo and something you can put in front of real customers.
Conversation and announcement cost very differently
Splitting your volume correctly between the two is the single biggest lever on your bill.
Two-way conversation
- Genuine dialogue — screening, qualification, surveys
- Every turn runs transcription and a language model
- Billed at the plan's conversation rate
- Use when you need an answer back
One-way announcement
- Plays a message and hangs up
- Payment reminders, appointment alerts, event notices
- No live reasoning, so substantially cheaper
- Use when you only need to inform
See pricing for the exact rates on each.
Where it works, and where it does not
Worth being honest about, because it decides where you deploy it.
Good at
- Volume people cannot absorb — a thousand screening calls in a day, same questions, same order
- Consistency — no drift between the first call of the morning and the hundredth of the evening
- Structured output — the same fields every time, sortable and comparable
- Speed to contact — a lead called within minutes converts far better than one called tomorrow
Poor at
- Emotionally sensitive conversations
- Complex negotiation
- Anything where a wrong answer creates legal or financial exposure
They work best as the first conversation — the qualifying, screening, reminding and routing layer that decides which calls a human should actually spend time on.
Where teams start
- Candidate screening — replace the first-round phone screen and get a ranked shortlist.
- Lead qualification — call every inbound enquiry in minutes and pass only the real ones to sales.
- Reminders and collections — announcement calls for due dates and appointments.
- Surveys and feedback — the same questions to everyone, structured answers back.
Choosing a platform
Most evaluations come down to five questions: does it sound natural enough that people stay on the line; does it handle your languages; what does a call really cost once telephony and model usage are included; can non-engineers change the script; and what do you get back after the call. If you are comparing options, the developer-platform comparison and India-focused comparison walk through those trade-offs.
