AssemblyAI ships a full voice-agent pipeline and a multi-LLM gateway, moving past speech-to-text.
AssemblyAI's recent shipping is dominated by two themes. The first is the new Voice Agent API — a complete pipeline (speech understanding, LLM reasoning, voice generation) over a single WebSocket at a flat $4.50/hour, running on Universal-3 Pro Streaming. The second is the LLM Gateway maturing as a hosted multi-LLM proxy: Claude Opus 4.7 is now available through it, and automatic model fallbacks landed in public beta. Around these, smaller releases include same-request unredacted transcripts on PII Redaction, Universal-2 accuracy improvements for Hebrew and Swedish, and a Medical Mode add-on for streaming transcription.
Chatwoot adds voice to close the last channel gap in its omnichannel support suite
Chatwoot is an open-source omnichannel customer-support platform spanning live chat, email, WhatsApp, social channels, and a help center, with an AI agent called Captain. The headline recent move is voice: phone and WhatsApp calls now run in beta, closing the one major channel gap in an otherwise text-complete product. Around it, steady investment in Captain (auto-syncing knowledge base, Custom Tools to call external APIs, mobile AI Assist), help-center depth (a documentation layout, LLM-aware articles, bulk and translation tooling), and agent-workflow polish (assignment policies, a Participating view).

AssemblyAI is repositioning from 'best-in-class speech-to-text' to 'end-to-end voice AI platform'. The Voice Agent API directly takes on Vapi, Retell, and the OpenAI Realtime API, and the bundled flat-rate pricing is a deliberate simplification — customers no longer need to track three meters across STT, LLM, and TTS providers. The LLM Gateway evolution rounds out the same idea: AssemblyAI as the vendor you call, with model variety and resilience handled inside.
Expect the Voice Agent API to gain richer agent-tooling primitives — function-calling, knowledge-base retrieval, latency tuning — and the LLM Gateway to add more frontier models and policy-routing. Vertical-specialized modes like Medical Mode are likely to expand to legal, finance, and customer support.

Chatwoot is rounding out into a complete omnichannel support suite — adding voice to become genuinely all-channel while making Captain more capable and self-maintaining through fresh knowledge bases, external tool calls, and handoff tuning. The throughline is cutting manual upkeep and channel-switching for support teams, and pushing AI deeper into both answering and knowledge management.
Expect voice to mature out of beta with call routing and reporting (the team flagged these as next), and Captain to keep gaining agentic capability, given the voice-beta roadmap notes and the Custom Tools and auto-sync cadence.
