| is the first iteration model trained using 10k hours of narrated audiobooks. It generates high-quality speech | |
| with features that can be controlled using a simple text prompt (e.g. gender, background noise, speaking rate, pitch and reverberation).</p> | |
| <p>Tips for ensuring good generation: | |
| <ul> | |
| <li>Include the term "very clear audio" to generate the highest quality audio, and "very noisy audio" for high levels of background noise</li> | |
| <li>Punctuation can be used to control the prosody of the generations, e.g. use commas to add small breaks in speech</li> | |
| <li>The remaining speech features (gender, speaking rate, pitch and reverberation) can be controlled directly through the prompt</li> | |
