Helia - AI voice agent

A voice agent that answers instead of a keypad menu.

Helia answers every call inside the PBX you already have. It understands what the caller needs, resolves recurring cases and hands the rest to the right colleague with transcript and recap.

In detail

Built for the phone.

Greetings and hours

  • The greeting changes with the time and day, with templates such as “Closed for the weekend”.
  • Weekly hours, holidays and special closures, per location or per agent.
  • Returning callers are greeted by name.
  • A non-interruptible greeting makes sure AI and recording notices are heard in full.

About 50 languages

  • Sticks to the languages you choose or follows the caller's.
  • Picks the opening language from the caller's international prefix.
  • The greeting is translated into every language it speaks.
  • Foreign-language transcripts reach your team already translated.

Voice and sound

  • A voice catalog by gender and accent, with previews and adjustable speed.
  • Expressive mode adds emotional nuance to the voice.
  • Office ambience, a typing sound while it looks things up, and noise suppression.
  • A glossary for brand names and acronyms, and rules such as “read phone numbers digit by digit”.

During the call

  • Warm transfer: Helia briefs your colleague first, who can accept or decline.
  • If nobody answers, it opens a callback ticket on its own.
  • Availability windows for every transfer destination.
  • Recognised or verified callers unlock extra information, documents and transfer targets.
  • After a booking, a confirmation SMS with your business name as the sender.

After every call

  • Transcript, audio recording and an AI summary.
  • The caller's category, sentiment and language.
  • An automatic outcome: answered, transferred, ticket opened, appointment booked or unsolved.
  • A suggested script for whoever calls back.
  • A signed webhook sends the call data to your own systems.
