AI captioning and translation platform for in-person, virtual, and hybrid events, supporting 100+ languages with broad streaming integrations.
Voiso is a cloud-based contact-center platform built for sales and customer-service teams, combining voice, SMS, and messaging channels with AI-driven analytics in a single workspace. Its speech analytics suite processes recorded call audio through speech-to-text and natural-language pipelines, transcribing calls into searchable text across more than ten languages, including English, Spanish, French, and Arabic. Transcripts can be navigated, searched, and flagged against predefined or custom keyword lists to support quality assurance, compliance, and agent training. Beyond raw transcription, the platform applies AI to score conversations on a 1-to-5 scale, detect sentiment and emotional cues, and automatically generate concise call summaries that capture key topics and outcomes without reviewing full recordings. It is aimed at call centers, BPOs, and outbound and inbound teams in industries such as fintech, travel, retail, and e-commerce. Other platform capabilities include a predictive dialer, IVR and routing flow builder, CRM integrations, call recording, and real-time performance dashboards. Speech analytics features are available on its Pro plan and higher.
