What is Speechmatics?
Speechmatics rolls its Enhanced English model across the stack, citing 89% WER gains on spellouts.
Speechmatics is a speech-recognition platform whose last quarter has been a coordinated rollout of its Enhanced Operating Point English model from containers through realtime and batch SaaS. The accuracy story is unusually concrete: 69% relative WER improvement on numbers, 89% on spellouts, 42% on mixed alphanumerics. Alongside the model work, the platform is adding voice-agent ergonomics — End of Utterance detection, prefer_current_speaker, speaker sensitivity — and broadening bilingual coverage.
What is Superhuman?
Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.
Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

Speechmatics
5.0COMMS
Speechmatics rolls its Enhanced English model across the stack, citing 89% WER gains on spellouts.
◆ Current state
Speechmatics is a speech-recognition platform whose last quarter has been a coordinated rollout of its Enhanced Operating Point English model from containers through realtime and batch SaaS. The accuracy story is unusually concrete: 69% relative WER improvement on numbers, 89% on spellouts, 42% on mixed alphanumerics. Alongside the model work, the platform is adding voice-agent ergonomics — End of Utterance detection, prefer_current_speaker, speaker sensitivity — and broadening bilingual coverage.
◆ Where it's heading
Two threads are running in parallel. Vertical depth: domain-specific models starting with medical, plus a growing list of bilingual code-switching pairs (Tagalog, Malay/English, Tamil/English, Mandarin/English, Arabic/English). Horizontal coverage: each model lands in containers first, then realtime SaaS, then batch SaaS, then appliance — containers function as the proving ground and SaaS as the broad rollout vehicle. The release notes also hint at voice agents being the primary use case Speechmatics is optimising for.
◆ Prediction
Expect more vertical-domain Enhanced models beyond medical (legal and finance are the obvious next targets) and a tighter packaging of the voice-agent primitives — End of Utterance, current-speaker locking, low-latency operating points — into something explicitly marketed as a voice-agent SDK or recipe.
Superhuman
6.3COMMS
Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.
◆ Current state
Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.
◆ Where it's heading
Superhuman is positioning itself as the email client AI agents operate, not just one humans use — its MCP, Draft Sync with Gmail and Outlook, and now a Codex plugin all point the same way. In parallel it keeps sharpening Split Inbox (reorder, hide-empty, a Reminders split) and mobile flow. The bet is agent-operability plus opinionated triage as the wedge against Gmail and Outlook.
◆ Prediction
Expect more agent surface — additional MCP hosts and agent-drivable actions — alongside continued Split Inbox personalization. The entries point to agentic email as the primary investment line.
