How this list was built
A company is on this list if LeadWave tags it as a voice, text-to-voice or voice-to-text company, or its description or website presents voice AI.
The data comes from LeadWave's database of SaaS and AI companies, last updated in November 2026. Companies that share a website are counted once. Headcount, funding and CEO come from public sources, so some fields are blank for smaller companies.
