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.

What is Telnyx?

Telnyx pulls the whole agent stack onto its own platform — and cuts voice AI loose from the phone line

Telnyx is shipping on two tracks at once. The steady one is model plumbing: GPT-5.4-mini, Kimi K3 on Inference, then GLM-5.2 and two GPT-5.6 variants, each slotted into Voice AI Assistants at a different cost-versus-reasoning point. The consequential one is structural — Edge Compute launched an Agent Runtime with Functions, KV, Cloud Storage, and Inference all GA, and Voice AI conversations now run over a direct WebSocket with no telephony involved. An Email API also entered beta, adding another channel to the same bill.

Krisp vs Telnyx: editorial side-by-side

K
Krisp
COMMS
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.

Telnyx pulls the whole agent stack onto its own platform — and cuts voice AI loose from the phone line

◆ Current state

Telnyx is shipping on two tracks at once. The steady one is model plumbing: GPT-5.4-mini, Kimi K3 on Inference, then GLM-5.2 and two GPT-5.6 variants, each slotted into Voice AI Assistants at a different cost-versus-reasoning point. The consequential one is structural — Edge Compute launched an Agent Runtime with Functions, KV, Cloud Storage, and Inference all GA, and Voice AI conversations now run over a direct WebSocket with no telephony involved. An Email API also entered beta, adding another channel to the same bill.

◆ Where it's heading

The company built its position on owning telephony infrastructure, and it is now spending that position rather than defending it. Letting assistants stream PCM16 audio straight from a web or mobile client means the voice product no longer requires a phone number, which opens it to developers who were never going to buy carrier services. Edge Compute is the other half: instead of renting Telnyx a channel and hosting the agent elsewhere, the agent's compute, state, and storage sit next to the media path. Channel breadth — SMS, voice, WhatsApp, now email — is being levelled under one API and one invoice.

◆ Prediction

Expect StatefulActor and CloudFS to reach GA next, and the Email API to leave beta and get folded into the same unified billing pitch. The model-add cadence should continue at roughly its current pace as new releases appear.
