Voicera

Voicera is a web platform and API for developers and enterprises that need multimodal analysis of digital conversations to generate credibility and sincerity insights from voice and video.

Key capabilities include:

• Multimodal fusion analysis that combines visual forensics (facial expressions, micro-expressions, biological stress signals) with vocal prosody (pitch, tone, jitter, hesitation) to assess credibility.
• Queryable Credibility/Sincerity scoring via API, designed to run in the background of a host product, returning JSON metadata for real-time streams (RTP) or async file uploads.
• Conversation intelligence outputs such as hesitation events, emotional state labels, and risk flags aligned to specific keywords and script topics, useful for role-play evaluation, sales call insights, recruiting, and legal or deposition review.
• Meeting workflows including transcription, speaker identification and attribution, summaries, action item extraction, and searchable archives (with integrations noted for Slack and Microsoft Teams).

Pricing: Tiered monthly plans starting around a low-cost starter tier (about $19/month) with limited minutes, scaling up to Pro and Enterprise plans with higher usage limits, advanced AI features, API access, and custom pricing for larger teams.

Notable for its API-first “truth layer” approach that emphasizes audio plus visual behavioral signals (not only transcripts), its stated use in multiple vertical solutions (Sales, HR, Legal, Law Enforcement), and its connection to Google Gemini (including participation in the Gemini API Developer Competition).
