What is AssemblyAI?
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.
What is Krisp?
Krisp has stopped being a noise-cancellation utility and become a contact-center voice platform.
Every entry in the last two months is filed under Call Center AI. The product now spans Voice Translation, Accent Conversion, Voice Security with deepfake detection and agent voice verification, Speech Analytics with screen recording, and an Enterprise Analytics Portal for sharing results with clients. Releases alternate between web-side batches roughly weekly and desktop app builds, and admin controls appear in nearly every one.
AssemblyAI vs Krisp: editorial side-by-side
AssemblyAI
0.0COMMS
AssemblyAI stopped selling transcription and started selling the whole voice agent.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Krisp
6.3COMMS
Krisp has stopped being a noise-cancellation utility and become a contact-center voice platform.
◆ Current state
Every entry in the last two months is filed under Call Center AI. The product now spans Voice Translation, Accent Conversion, Voice Security with deepfake detection and agent voice verification, Speech Analytics with screen recording, and an Enterprise Analytics Portal for sharing results with clients. Releases alternate between web-side batches roughly weekly and desktop app builds, and admin controls appear in nearly every one.
◆ Where it's heading
The direction is real-time voice manipulation sold to contact centers, not consumers. Accent Conversion now runs on both sides of a call, translation gained speed control and a spelling mode for names and numbers, and the language list keeps growing. Voice Security is the defensive counterpart — the same synthesis capability that powers accent conversion is what makes deepfake detection necessary, and Krisp is selling both sides. The steady stream of admin controls, audit logs, and automated data cleanup shows an enterprise procurement checklist being worked through.
◆ Prediction
Expect the language and accent model coverage to keep widening and Voice Security to move from paid trial toward general availability. The portal API gaining audit logs suggests more of the admin surface will become programmatic.
