State-of-the-art Deep Neural Network TTS Engine developed for Kannada
RaGaVeRa's Kannada TTS exceeds the quality of Google and Nuance Kannada TTS
Comparison of the quality of RaGaVeRa’s TTS against Google’s WaveNet and Nuance’s Kannada TTS as assessed by 55 natives of Kannada. RaGaVeRa’s TTS got a mean preference score of 78.2% in contrast to 13.1% for Google’s TTS and 5.1% for Nuance’s TTS.
Our Kannada TTS was able to achieve an MOS of 4.42 ± 0.53 when compared to the ground truth 4.55 ± 0.56 based on the evaluation of 25 Kannada natives.
A survey was conducted to compare our synthesized speech with the human speech and it was seen that people preferred the synthesized speech over human speech.
