NVIDIA NeMo Releases the T5-TTS Model for Advanced Speech Synthesis
NVIDIA NeMo has introduced the T5-TTS model, a cutting-edge innovation in text-to-speech (TTS) technology. This new model represents a significant leap forward in the field of speech synthesis, leveraging large language models (LLMs) to create more precise and natural-sounding speech output.
The Significance of Large Language Models in Speech Synthesis
Large language models have transformed natural language processing (NLP) by enabling the generation of coherent text. These models have now been adapted for speech synthesis, capturing the intricacies of human speech patterns and intonations. This adaptation has resulted in speech synthesis models that can produce more natural and expressive speech, opening up new possibilities for a variety of applications.

Overview of the T5-TTS Model
The T5-TTS model utilizes an encoder-decoder transformer architecture for speech synthesis. The encoder processes text input, while the auto-regressive decoder uses a reference speech prompt from the target speaker to generate speech tokens. These tokens are generated by attending to the encoder’s output through the transformer’s cross-attention heads, which are designed to align text and speech. Despite their effectiveness, these heads can encounter difficulties, especially with input text containing repeated words.
Addressing the Challenge of Hallucinations
One of the challenges in TTS systems is the occurrence of hallucinations, where the generated speech deviates from the intended text, resulting in errors such as mispronunciations or incorrect words. These inaccuracies can affect the reliability of TTS systems in critical applications like assistive technologies and customer service. The T5-TTS model tackles this issue by aligning textual inputs with speech outputs more efficiently, significantly reducing hallucinations.
