Model Introduction

ViiTor ASR is more than a basic speech-to-text model. It is optimized for real-world content scenarios such as livestreams, videos, online courses, meetings, gaming commentary, and interactive conversations where speech is often noisy, conversational, and filled with names, slang, and domain-specific terms. In these scenarios, recognition is not only about capturing what was said. The model also needs to understand context, spoken expressions, pauses, rhythm, and tone. ViiTor ASR combines speech recognition, streaming translation, subtitle generation, and paralinguistic understanding to produce results that are more stable and closer to real speech. It is designed for two types of tasks: real-time understanding, such as live subtitles, meeting transcription, and cross-language interaction; and content production, such as video subtitles, course transcription, podcast structuring, and multilingual localization.

Core AI Capabilities

Complex Speech Content Recognition

Real-world speech is rarely clean or standardized. Livestreams, videos, gaming commentary, meetings, and interviews often contain names, nicknames, abbreviations, slang, game titles, brand terms, and spontaneous conversational expressions. ViiTor ASR is optimized for complex speech content, with enhanced recognition for proper nouns, trending words, and domain-specific vocabulary, helping the model perform more reliably in real content scenarios.

Streaming End-to-End Speech Translation

In real-time scenarios, users cannot wait until a full sentence or paragraph ends before seeing the translation. ViiTor ASR supports streaming end-to-end speech translation, continuously producing recognition and translation results while speech is being spoken. This is suitable for live subtitles, multilingual meetings, real-time video understanding, and interactive conversations. Users can listen and read source and translated content at the same time.

Paralinguistic Information Understanding

When people speak, meaning is carried not only by words, but also by tone, pauses, pace, hesitation, emphasis, and conversational expressions. ViiTorContext captures these paralinguistic signals, making recognition and translation closer to real spoken language. In livestreams, interviews, interactive conversations, and virtual human scenarios, this helps the system better understand the speaker's intent.
