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 moves call transcripts and live captions to cloud transcription in KrispCX 2.84.4.

Krisp sells a Call Center AI suite to BPOs and contact centers: Accent Conversion, Voice Translation, QA scoring, deepfake and fraud detection. KrispCX 2.84.4 adds cloud transcription in beta for more accurate transcripts and Live Captions, plus in-call hints when the Krisp microphone is in use; the source note is truncated. October brought Conference mode for Voice Translation and a Fraud Detection beta.

AssemblyAI vs Krisp: editorial side-by-side

A0.0

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.

5.0

Krisp moves call transcripts and live captions to cloud transcription in KrispCX 2.84.4.

◆ Current state

Krisp sells a Call Center AI suite to BPOs and contact centers: Accent Conversion, Voice Translation, QA scoring, deepfake and fraud detection. KrispCX 2.84.4 adds cloud transcription in beta for more accurate transcripts and Live Captions, plus in-call hints when the Krisp microphone is in use; the source note is truncated. October brought Conference mode for Voice Translation and a Fraud Detection beta.

◆ Where it's heading

Releases arrive on a two-week cadence and keep stacking agent-assist features on the live call, from translation to fraud signals to captions. The September move to free-to-try has been followed by incremental depth rather than new product lines.

◆ Prediction

Expect more of the live-call layer to move to cloud processing, with QA scoring and translation likely reusing the new transcription. The truncated notes leave the scope of the cloud beta unclear.
