CallMiner is an enterprise speech and conversation analytics platform, built around its Eureka product, that captures and analyzes customer interactions across voice and digital channels. It records and transcribes calls into text, then applies acoustic and linguistic AI to surface sentiment, emotion, intent, and behavioral signals — quantifying frustration, effort, satisfaction, and confidence rather than sampling a fraction of conversations. Designed for contact centers and large enterprises, it spans modules for analysis, automated agent scoring and coaching, real-time guidance during live calls, automated redaction of sensitive data, multilingual translation, and interactive dashboards. CallMiner ingests voice, chat, email, surveys, social media, and screen recordings, applying scoring models to isolate compliance risks, fraud, quality issues, and sales outcomes. It also includes generative and agentic AI features such as automatic category creation, contact summarization, and natural-language discovery. The platform is used across healthcare, finance, retail, insurance, and BPO sectors, and was named a leader in The Forrester Wave: Conversation Intelligence Solutions for Contact Centers, Q2 2025.
Best suited for
Letterly is a voice-to-text application that converts spoken words into clean, structured written text. Aimed at professionals, students, content creators, and anyone who prefers talking to typing, it lets users record speech directly in the app or dictate into other apps, then automatically transcribes the audio. Beyond raw transcription, Letterly applies AI rewriting so a single recording can become an email, a summary, a social post, a task list, a journal entry, or a meeting recap, using preset styles or custom instructions. It automatically detects and transcribes a wide range of languages and can handle mid-sentence language switching. For meetings and interviews, it offers speaker separation and can generate summaries from a recording. The app supports extended recordings, offline and screen-off dictation, quick-record widgets, and live sync across devices, including Apple Watch. It also integrates with external tools via Zapier and webhooks. Letterly states that user data is kept private and not used to train AI models. It runs on iOS, Android, Mac, Windows, and Web.
