Seamless has launched its next-generation AI language translation system, which preserves expressions and offers low-latency streaming in voice-to-voice translations. This system supports multiple languages, including English, Spanish, German, French, Italian, and Chinese, enabling the transmission of genuine emotions and styles across languages. Additionally, tools for metadata and data alignment have been released, expanding the collection of translation data. SeamlessExpressive focuses on under-explored elements of speech such as prosody, while SeamlessStreaming enables real-time conversations with groundbreaking latency of approximately two seconds.
