Best AI Voice & Speech for enterprise teams

Last verified:

Crail tracks 6 AI Voice & Speech vendors that list enterprise teams as a fit. These are the 5 that rank highest once the list is weighted for enterprise teams, and each one is shown with compliance evidence, deployment control and data residency — the facts that decide the shortlist at this size, rather than the same summary on every page.

How this list is weighted for enterprise teams

  • 60% of the vendor's Crail agent-readiness score
  • up to 24 points for published compliance certifications (8 per certification)
  • 10 points for documented SSO/SAML support
  • 6 points for a documented audit log

Startups and small businesses share the price-and-self-serve weighting; midmarket and enterprise share the compliance weighting. The full rules are on the methodology page.

FAQ

How is this AI Voice & Speech ranking calculated for enterprise teams?

This is not the raw agent-readiness leaderboard. Crail scores the 6 AI Voice & Speech vendors it tracks that fit enterprise teams, using 60% of the vendor's Crail agent-readiness score; up to 24 points for published compliance certifications (8 per certification); 10 points for documented SSO/SAML support; 6 points for a documented audit log. Murf AI ranks first once the enterprise teams weighting is applied, even though ElevenLabs scores higher on raw agent-readiness (74/100 against Murf AI's 66/100), because the weighting adds points that score does not cover.

Which of these can run inside our own cloud or data center?

Deepgram (cloud, self-hosted, on-prem) and Cartesia (cloud, on-prem, BYOC) document deployment outside the vendor's own cloud. Murf AI, ElevenLabs and AssemblyAI are cloud-only. Data-residency options are published by Murf AI (US), ElevenLabs (US, EU, India), Deepgram (US, EU, Australia) and AssemblyAI (US, EU).

What compliance certifications do these vendors publish?

Murf AI: SOC 2 Type II, ISO 27001, ISO 42001, GDPR, CCPA. ElevenLabs: SOC 2, GDPR. Deepgram: SOC 2 Type 1, SOC 2 Type 2, HIPAA, PCI, GDPR, CCPA. AssemblyAI: SOC 2 Type 2, ISO 27001, HIPAA (BAA available), GDPR. Crail found no published certifications for Cartesia.
