Product Introduction

1. Sokuji is a browser extension and desktop application that leverages OpenAI's Realtime API and GPT-4o to provide instantaneous speech translation during live video calls. It processes audio input in real time, translates it across languages, and routes the translated audio directly into video conferencing platforms. The product operates as a virtual audio device for desktop use and integrates natively with Google Meet via its browser extension.
2. The core value of Sokuji lies in eliminating language barriers during real-time communication by providing seamless, AI-powered interpretation without requiring manual transcription or post-call processing. It enables multilingual participants to engage in natural conversations during video meetings by translating spoken words with sub-second latency.

Main Features

1. Sokuji utilizes GPT-4o's multimodal capabilities to analyze speech context, tone, and idiomatic expressions, delivering translations that preserve conversational intent rather than providing literal word-for-word conversions. The system supports continuous audio stream processing with an average latency of 1.2 seconds from speech input to translated output.
2. The desktop application creates virtual audio devices that intercept system-wide microphone input, translate it through OpenAI's API, and output the translated audio to any video conferencing software (e.g., Zoom, Teams). Simultaneously, the browser extension version directly integrates with Google Meet's audio pipeline for zero-configuration deployment.
3. Audio routing architecture employs packet prioritization and echo cancellation algorithms to ensure translated audio maintains synchronization with lip movements and prevents feedback loops during bidirectional translations. Users can select source and target languages through a floating control panel that overlays video conferencing interfaces.

Problems Solved

1. Sokuji addresses the critical challenge of real-time cross-language communication in professional environments where delayed translations disrupt meeting flow. Traditional solutions require pre-scheduled human interpreters or produce disjointed translations that lag behind live conversations.
2. The primary target users include global enterprise teams conducting daily standups, customer support agents handling multilingual inquiries, and educators delivering remote instruction to international student groups. It also serves government agencies and healthcare providers requiring HIPAA-compliant real-time interpretation.
3. Typical scenarios involve a Japanese engineer explaining technical specifications to German stakeholders during a product demo, a Spanish-speaking sales representative negotiating with Mandarin-speaking clients, or a Ukrainian refugee coordinator communicating with English-speaking aid organizations via Google Meet.

Unique Advantages

1. Unlike conventional translation tools like Google Translate or Microsoft Translator, Sokuji directly injects translated audio into video call applications as a virtual microphone input, bypassing the need for separate translation devices or secondary audio channels. This integration allows simultaneous interpretation without requiring participants to switch between multiple apps.
2. The proprietary audio routing engine combines WebRTC's noise suppression with custom jitter buffers to maintain audio continuity even under unstable network conditions (tested up to 30% packet loss). GPT-4o's contextual understanding enables accurate translation of industry-specific jargon, acronyms, and culturally nuanced phrases that generic translation APIs often misinterpret.
3. Competitive differentiation stems from dual deployment options – the desktop app's system-wide compatibility complements the browser extension's tight Google Meet integration. Unlike cloud-only competitors, Sokuji's hybrid architecture processes sensitive audio data locally before encrypted API transmission, complying with GDPR and CCPA regulations for enterprise deployments.

Frequently Asked Questions (FAQ)

1. What video conferencing platforms does Sokuji support? Sokuji's browser extension currently supports Google Meet, while the desktop application works with any video software that recognizes virtual audio devices, including Zoom, Microsoft Teams, and Discord. Webex and Slack compatibility are under active development.
2. How many languages can Sokuji translate between? The system supports all languages available in OpenAI's Whisper and GPT-4o models, including but not limited to English, Mandarin, Japanese, Spanish, French, German, and Arabic. Regional dialects and technical terminology require enabling the "Enhanced Context" mode in advanced settings.
3. Does Sokuji introduce noticeable audio delay during translation? Average latency is maintained at 1.2 seconds through optimized audio chunking and parallel API processing, which is below the 1.5-second threshold for maintaining conversational flow according to ISO/TS 18138 standards. Network latency above 300ms may require adjusting the buffer size in the desktop app's configuration panel.
4. Can Sokuji operate without an internet connection? Real-time translation requires connectivity to OpenAI's API endpoints due to the computational demands of GPT-4o. The desktop app includes a local cache that stores 15 seconds of audio during temporary network disruptions, with automatic resynchronization upon connection recovery.
5. How do I set up the virtual audio devices for desktop use? After installation, Sokuji creates "Sokuji Input" (translated audio) and "Sokuji Output" (original audio) devices in your OS sound settings. Configure your video conferencing app's microphone to use "Sokuji Input" and set speakers to "Sokuji Output" to enable bidirectional translation without echo interference.
