What is AssemblyAI?
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.
What is Krisp?
Krisp is repositioning from noise cancellation to a contact-center voice-AI platform
Krisp's updates are now almost entirely 'Call Center AI': a new Voice Security line against AI voice fraud (deepfake detection, agent voice protection), expanding Voice Translation, Speech Analytics with Salesforce-fed scoring, Accent Conversion, and admin controls for translated calls. The consumer noise-cancellation roots have receded from the feed.

AssemblyAI
6.3COMMS
AssemblyAI ships a full voice-agent pipeline and a multi-LLM gateway, moving past speech-to-text.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Krisp

Krisp is repositioning from noise cancellation to a contact-center voice-AI platform
◆ Current state
Krisp's updates are now almost entirely 'Call Center AI': a new Voice Security line against AI voice fraud (deepfake detection, agent voice protection), expanding Voice Translation, Speech Analytics with Salesforce-fed scoring, Accent Conversion, and admin controls for translated calls. The consumer noise-cancellation roots have receded from the feed.
◆ Where it's heading
The product is moving up-market into contact centers, stacking real-time voice translation, analytics, agent assist, and now fraud defense into a CCaaS-adjacent suite. Voice Security is the newest and sharpest extension of the capability surface.
◆ Prediction
Expect Voice Security and Voice Translation to keep expanding, with deeper CRM integrations like the Salesforce link feeding analytics scoring.
