What it is
Voci Technologies, acquired by Medallia in 2021, builds high-throughput ASR for enterprise call analytics. V-Blaze is the transcription engine; V-Spark is the analytics layer with redaction, sentiment, agent scoring, and call categorization. Most deployments are on-prem or in customer VPCs to meet contact-center compliance requirements. Now sold as part of Medallia's contact-center suite. Best fit: large contact centers needing high-throughput on-prem asr with pii redaction. Caveats: enterprise sales only; not a self-serve product; legacy v-spark / v-blaze branding. Feature flags from vendor docs: speaker diarization, word-level timestamps, streaming, HIPAA-eligible under BAA. Directory tags: voice-intel, call-analytics, on-prem. Last vendor-page check: 2026-05-12.
Watch out for: Enterprise sales only; not a self-serve product; legacy V-Spark / V-Blaze branding.
