Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Voicegain when building telephony voice bots and call analytics matters most. Run both through a week of actual calls to see which suits your workflow.

Speech-to-text and ASR platform with developer APIs plus a private LLM-powered meeting notetaker.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

Voicegain is a speech recognition company that offers both speech-to-text APIs for developers and a packaged meeting assistant called Transcribe. Its ASR engine supports batch transcription of recorded files and real-time streaming for live audio, and it can be deployed in the cloud, in a customer's virtual private cloud, or on-premises, which appeals to organizations with strict data-control or privacy requirements. On the developer side, Voicegain provides speech-to-text, speech-analytics, and telephony-bot APIs that can transcribe audio and analyze it for sentiment, named entities, topics, and intent. Its meeting product, Transcribe, is described as a private, LLM-powered meeting notetaker that captures audio from video-meeting browser tabs and uploaded recordings, integrates with Zoom, Microsoft Teams, and Google Meet, and automatically identifies topics and highlights from a conversation. A Windows desktop app supports Zoom local recordings. Because Voicegain spans both an underlying ASR platform and an end-user meeting tool, it suits teams that want either to build on its APIs or to use a ready meeting notetaker with flexible deployment and a focus on keeping data private. Pricing varies by plan. Check the official website for current pricing.
