AssemblyAI stopped selling transcription and started selling the whole voice agent.
AssemblyAI shipped a Voice Agent API that delivers speech understanding, LLM reasoning, and voice generation over a single WebSocket at one $4.50/hr rate, built on its own models. Around it, streaming speaker diarization got an accuracy upgrade with per-word labels across US and EU regions, the LLM Gateway gained a json-repair post-processing step, and PII redaction can now return redacted and unredacted transcripts in one request.
Salesmsg now runs the entire sales-to-NPS loop in one thread — outbound, AI reply, booking, survey, and routing.
Salesmsg has expanded well past SMS messaging into a full-stack sales communication platform. AI agents handle text and voice, execute actions (send SMS, log notes, tag callers, escalate with context), and now route contacts based on NPS scores. The recent addition of native surveys closes a loop that previously required a separate CX tool.

The supporting releases are all steps up the stack from raw transcription: an LLM gateway with output repair, speaker labels precise enough for agent turn-taking, and redaction that no longer forces a second call. The Voice Agent API is where they converge — AssemblyAI is pricing an outcome per hour rather than an API per minute, and owning the models underneath is what makes that pricing defensible.
Expect the agent pipeline to gain configuration depth — interruption handling, turn detection, or telephony ingress — since a single all-in rate only holds up if the pipeline handles real call conditions. The feed also republishes launches a day apart, so entry counts here run ahead of actual releases.

The recent addition of native surveys closes a loop that previously required a separate CX tool.
Every release reduces a manual touchpoint. AI agents now handle opt-outs, book meetings from warm replies, write handoff summaries, log post-call notes, and route contacts by survey score — all without rep intervention. The trajectory is toward a fully autonomous outreach-to-feedback cycle where humans review outcomes rather than manage steps.
The next move will likely be survey-score-triggered AI agent sequences — automatically enrolling detractors in win-back flows and promoters in referral asks based on NPS results. The routing logic already exists; wiring it to agent automation is the obvious completion.
