Deep Voice 3 vs Narakeet

Deep Voice 3 is an open source text-to-speech system that uses a fully convolutional neural network to convert text into natural-sounding speech. It supports both single-speaker and multi-speaker models, allowing it to generate speech in various voices and accents. The system is designed to scale efficiently, handling large datasets and training quickly compared to traditional TTS models.

The architecture includes an encoder that processes text inputs, an attention-based decoder that predicts mel-scale spectrograms, and a converter network that generates vocoder parameters for waveform synthesis. This design helps produce clear and natural speech with fewer mispronunciations. Deep Voice 3 also supports training on phoneme, character, or mixed inputs, which improves pronunciation accuracy.

Recent implementations have demonstrated the model's ability to synthesize speech from multiple speakers with distinct accents and ages, showcasing its versatility. Audio samples from various English accents, including Southern England and Scottish, highlight its adaptability to different speech styles.

Deep Voice 3 is suitable for developers and researchers interested in building scalable, high-quality TTS applications. Its open source nature allows customization and experimentation with different model configurations and datasets.

While the core technology remains consistent with the original design, ongoing community efforts focus on improving training efficiency and expanding multi-speaker capabilities. The system's modular structure facilitates integration with other speech processing tools and vocoders.

Overall, Deep Voice 3 offers a balance of speed, scalability, and speech quality, making it a valuable resource for those working on speech synthesis projects that require flexibility across voices and languages.
