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 Soniox when building voice agents and dictation features into apps matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Multilingual speech AI platform offering real-time and async speech-to-text and translation APIs for meetings and voice apps.
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.

Soniox is a multilingual speech AI platform that provides speech-to-text, translation, and text-to-speech APIs aimed at developers building voice-enabled applications, including meeting transcription, voice agents, dictation, and call-center tools. Its speech recognition supports real-time streaming with low latency as well as asynchronous processing of recorded files, and it covers a broad set of languages with the ability to handle conversations where speakers switch languages mid-sentence. For meeting and multi-party scenarios, Soniox offers speaker separation so transcripts can attribute speech to individual participants, along with handling of names, alphanumerics, and domain-specific terms. The platform also includes real-time speech translation across many language pairs, which is useful for international calls and meetings. Soniox markets enterprise-grade compliance, including SOC 2 Type 2, ISO 27001, HIPAA, and GDPR, and offers multi-region deployment with data-residency options and a privacy-oriented architecture where audio is processed in real time. Because it is delivered as APIs and SDKs, organizations typically embed Soniox into their own products rather than using it as a standalone meeting application. Pricing varies by plan. Check the official website for current pricing.
