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.
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
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.
Telnyx

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.
