Speech core

Speech in, a decision, speech out.

Streaming speech to text, an agent brain, turn taking and text to speech run as one pipeline behind every call, tested and swappable without slowing the conversation.

One turn, end to end

The same pipeline, every call

Channels arrive on the left, the speech core answers in the middle with memory and tools at its shoulders, and the outcome leaves on the right. The whole path is tested and monitored release after release.

Inside the core

What the speech core actually does

Each caller turn moves through five steps, from the line to the reply. Two guarantees hold across all five.

  1. The call connects

    SIP, virtual PBX and connected telephony routes carry the call into the core, and outbound calling rules apply before a number is dialed.

    See telephony in depth
  2. Speech becomes text

    The call is transcribed in real time, then corrected and normalized before the agent reasons, so an accent, an interruption or a mid-sentence pause does not skew what was said.

  3. The agent reasons

    It reads intent with memory of earlier turns and other channels, checks guardrails and policy before it speaks or acts, and uses the tools it needs mid-call.

  4. Turns feel natural

    A dedicated model runs barge-in, so the caller can cut in mid-sentence, and end-of-turn detection, so the agent does not talk over a pause or sit through a finished answer.

  5. Text becomes a voice

    Each brand picks a curated voice from the library, with a persona for pace, formality and tone, accent correction and a pronunciation dictionary for names, places and product terms.

On every turn

Fast replies, no silence

When a tool or model runs long, a short, natural filler from DRING's approved set keeps the turn moving.

  • Replies keep a natural pace, whichever vendor sits behind them
  • Fillers never appear in an apology, a number or the closing

Model routing and failover

Speech, language and voice models are chosen per agent and per language, and a workflow can route to a different model without a re-platform.

  • If a provider has an issue, the call can fail over to a working one
  • A stronger service goes live only after clearing the regression suite the whole stack runs

Shared with chat

The same brain, speaking or writing

Voice is not a separate system from chat. The memory, the guardrails and the outcome record underneath are the same.

One memory

A person recognized on a call is recognized in a message, and a conversation that starts on the phone can continue on WhatsApp without the customer repeating themselves.

Same guardrails

Prompt defense, fact checking and data masking run on a spoken reply exactly as they run on a written one, not a lighter version of the rules.

Same outcome record

A call closes as the same structured record as a chat: a result, a score and the fields your team defined, written to your CRM.

FAQ

Speech core questions.

Does the speech core share memory and guardrails with chat?+

Yes. A call and a message about the same customer share one case and one memory, and prompt defense, fact checking and data masking run the same way on both.

What happens if a reply is slow to generate?+

A short, natural filler from DRING's approved set keeps the turn moving while the response finishes behind it, never in an apology, a number or the closing.

Can the speech to text and text to speech models be changed?+

Yes. Speech-to-text, language and text-to-speech providers are each swappable per agent and per language, and a workflow can route to a different model without a re-platform.

How does the agent know when a caller has finished talking?+

A dedicated turn-taking model handles it: barge-in lets a caller interrupt mid-sentence, and end-of-turn detection tells the agent when the caller has actually finished, so it does not talk over a pause or sit through a completed answer.

Where do the voices come from?+

From a curated library, chosen per brand and per language, with a persona set for pace, formality and tone, accent correction applied to the voice, and a pronunciation dictionary for names, places and product terms.
