Streaming T5-based Text-to-Speech Synthesis with Limited Lookahead

S5-TTS, a streaming variant of T5-TTS, has been introduced to address latency issues in text-to-speech synthesis by enabling word-by-word incremental speech generation. It utilizes encoder-decoder language modeling and a lookahead-causal masking mechanism with Conv-based auxiliary attention, achieving comparable quality to full-context T5-TTS while significantly reducing end-to-end response latency. This development is crucial for practitioners in conversational AI, as it allows for immediate speech generation and maintains intelligibility and speaker similarity, enhancing user experience in real-time applications.
