How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and InnoCaption when making and receiving captioned phone calls independently matters most. Run both through a week of actual calls to see which suits your workflow.

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.

InnoCaption is a captioning service built for deaf and hard-of-hearing users in the United States that displays real-time text of what others say during phone calls and video meetings. Users speak with their own voice and read captions generated either by live human stenographers or by automated speech recognition, switching between the two as needed. The mobile apps run on iOS and Android phones and tablets, and InnoCaption Web brings captioning to a browser. For virtual meetings, the InnoCaption Bot can join Zoom, Google Meet, Microsoft Teams, and Webex calls from a pasted meeting link, showing live captions with speaker identification; a dial-in method is also supported. Past call and meeting transcripts are saved and can be reviewed, emailed, or shared via a live-caption link that others open in any browser without logging in. The service is FCC-certified and funded through the federal Telecommunications Relay Services Fund. It is aimed at individuals with hearing loss who need accessible phone and meeting communication.
