How Hosiqo compares and tests toolsFinal recommendation
Shortlist AutoMemo when capturing and transcribing in-person business meetings matters most, and Soniox when building voice agents and dictation features into apps matters most. Try them side by side on real calls before deciding — needs vary by team.

Multilingual speech AI platform offering real-time and async speech-to-text and translation APIs for meetings and voice apps.
AutoMemo (オートメモ) is a transcription AI developed, sold, and supported by Sourcenext Corporation in Japan. It is built around a multi-surface approach: users can capture audio through a web browser app, a dedicated smartphone app, or standalone hardware voice recorders (the AutoMemo S and AutoMemo R devices), and the captured audio is automatically converted to text. The service uses a Whisper-based speech recognition engine, automatically inserts punctuation, removes filler words such as Japanese hesitation sounds, and recognizes speakers so that transcription results are divided into speaker blocks. On top of the transcript, AutoMemo can automatically generate summaries and extract to-do items and deadlines, and it has added features such as AI-generated titles for recordings. Audio and transcripts are saved to the cloud for later editing, searching, and sharing. AutoMemo positions itself for business meetings, interviews, and lecture capture in Japanese-language workflows, and offers a limited free transcription allowance with paid plans for higher usage. It remains actively developed and marketed in 2025/2026. Pricing varies by plan. Check the official website for current pricing.

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.
