BASE TTS: Audio samples

Audio samples for the paper "BASE TTS: Lessons from building a billion-parameter text-to-speech model on 100K hours of data".

Abstract: We introduce a text-to-speech (TTS) model called BASE TTS, which stands for Big Adaptive Streamable TTS with Emergent abilities. BASE TTS is the largest TTS model to-date, trained on 100K hours of public domain speech data, achieving a new state-of-the-art in speech naturalness. It deploys a 1-billion- parameter autoregressive Transformer that converts raw texts into discrete codes ("speechcodes") followed by a convolution-based decoder which converts these speechcodes into waveforms in an incremental, streamable manner. Further, our speechcodes are built using a novel speech tokenization technique that features speaker ID disentanglement and compression with byte-pair encoding. Echoing the widely-reported "emergent abilities" of large language models when trained on increasing volume of data, we show that BASE TTS variants built with 10K+ hours and 500M+ parameters begin to demonstrate natural prosody on textually complex sentences. We design and share a specialized dataset to measure these emergent abilities for text-to-speech. We showcase state-of-the-art naturalness of BASE TTS by evaluating against baselines that include publicly available large-scale text-to-speech systems: YourTTS, Bark and TortoiseTTS.

Below are selected samples produced by the model. There's no annotation on the input text and no post-processing on the audio.

"Uh, are you sure about this?" Tim asked nervously, looking at the steep slope before them. "Whoa, it's higher than I thought," he continued, his voice filled with trepidation. "Aha, but look at the view," Emily responded with excitement, "it's worth the climb!"
