DeepL Voice 采用新 Aure 模型，实时翻译可保留语调与语速

DeepL Voice's real-time translations are about to sound a lot more natural. The company's new Aure model carries over tone, emotion, emphasis, and speaking pace from the original speaker's voice into the target language. Until now, DeepL Voice generated translated speech from a static voice sample captured at the start of a conversation. That meant it couldn't pick up on mood shifts or sarcasm. Aure works differently, continuously analyzing both the translated text and the original audio as the conversation unfolds.

During training, DeepL separates voice identity, speech melody, and content so each component can be transferred into the new language independently. Reinforcement learning keeps accents out of the output. Aure runs automatically in DeepL Voice for Online Meetings, In-Person Conversations, and the DeepL API. At launch, the model supports English, German, Spanish, French, Italian, Japanese, Portuguese, and Korean.

DeepL first rolled out voice preservation in September. In May, the company cut about 250 jobs to restructure around smaller, AI-powered teams as part of what it called becoming an "AI-native" company. DeepL also acquired the team behind audio streaming specialist Mixhalo to bolster its real-time speech translation. Block is chasing a similar goal of capturing meaning beyond words. The company recently unveiled Dessa, a speech model designed to detect emotions and sarcasm directly from audio.
