Voice agent
A voice agent is an AI agent that converses through speech instead of text. The user talks; the agent transcribes, reasons, replies in synthetic speech, and optionally pushes follow-up artifacts (like a SMS link) back to the user's phone.
Why it matters
Voice is the oldest interface and the hardest one to do well. The pipeline has six failure modes (microphone capture, voice activity detection, speech-to-text, language model reasoning, text-to-speech synthesis, output playback) and each one has its own latency budget. A voice agent that takes longer than three seconds to start responding feels broken. One that starts responding instantly but with an unrelated answer feels worse.
The category is finally working in 2026 because three things matured at once: streaming STT (so the agent can start reasoning before the user finishes talking), low-latency TTS (so the agent can start speaking before it has finished generating the reply), and voice-cloning that produces a believable specific voice rather than a generic text-to-speech voice. The right voice agent is mostly indistinguishable from a competent human across a 90-second call.
The other unlock is the cross-channel handoff. A voice agent that can text the caller a follow-up link mid-call (a Stripe payment link, a calendar invite, a confirmation) is far more useful than a voice agent that can only speak. The user hangs up with something on their phone, not just a memory of a conversation.
How Ajeris handles this
Ajeris voice runs on two surfaces. The personal voice surface comes through the Alexa skill agent when the user has linked an Echo, and through inbound voice calls to the agent's number. The business voice surface is the voice receptionist Maya, who answers calls to your business number, books appointments, and sends invoices. Both surfaces use streaming STT, voice cloning for the user-or-business voice, and the same per-user agent that runs the text channels. Mid-call the agent can push to phone a follow-up SMS or WhatsApp link.
