Fast voice AI, engineered end to end.

Our engineers tune every layer of the call for speed, so topdoer.ai agents answer in well under a second, sound like people, and get better with every call.

“I need to move my appointment.”

Of course. First, can you confirm your date of birth?

Latency

Speed is engineered, not bought.

Most voice AI chains separate vendors together over the public internet, and every call waits on each hop. We tune telephony, speech recognition, the language model, and the voice as one streaming pipeline, which cuts the wait dramatically.

1 tuned pipeline
Streaming end to end

  1. 1 Compute

    Reserved for your calls. Nothing else runs on it.

  2. 2 Releases

    Pinned to you. When you promote one, it rolls out gradually.

  3. 3 Network

    Your private cloud or on-premise, behind your firewall.

Infrastructure

Your calls run on your own machines.

Enterprise customers run on dedicated infrastructure, in a private cloud or on-premise. Another company's traffic can never slow your calls.

Voice

Answers in the pause a person would take.

Natural voices chosen for phone audio, in English and Spanish, on a pipeline our team tunes for response time, so the agent answers in well under a second, the pause a caller expects from a person.

Caller

Guardrails

Some steps are never skipped.

Identity checks, disclosures, and confirmations run exactly as written. Everything around them stays a natural conversation.

  1. Greeting

    “Thanks for calling Bahía Dental. How can I help?”

    Natural conversation
  2. Verify identity

    Name and date of birth must match the record before anything else.

    Always runs
  3. The caller's request

    Moving Friday's cleaning, asked however the caller likes.

    Natural conversation
  4. Read the disclosure

    The recording notice is read word for word.

    Always runs
  5. Finding a time

    The agent offers open slots and handles follow-up questions.

    Natural conversation
  6. Confirm the details

    Date, time, and location are repeated back before the call ends.

    Always runs

Releases

Nothing reaches callers untested.

A new version can't go live until its test calls pass. Then it takes more calls in steps.

Analytics

Every call, counted and searchable.

Where calls come from, how many the AI handled, and how long they took, for every agent and every day.

Improvement

A bad call becomes a better agent.

Flag a call. We find the cause, draft a fix, and test it on the call that failed before it ships.

  1. 1A call goes wrong

    A caller gets the wrong answer, and someone on your team flags it.

  2. 2We find the cause

    The transcript and every tool call show exactly where it went off track.

  3. 3We draft a fix

    A change to the prompt, a step, or the knowledge it reads from.

  4. 4Tested on that call

    The fix replays the failed call and ships only when it passes.

Telephony

Numbers, transfers, and texting run on Twilio's carrier network. Get a new local number or bring your own Twilio account, with no separate carrier to wire up.
