Almost Unsupervised Text to Speech and Automatic Speech Recognition
Table 3: The PER on ASR with different amount of paired data for our method.

S4SS3SSS0Px3 Varying Paired Data Lastly, we vary the available paired speech and text data for almost unsupervised learning on TTS and ASR, where we choose 100, 200, 300, 400 and 500 data each and verify the performance of our method. When there are 500 paired data, our method can achieve 4.4% PER, very close to the PER of the Supervised system (2.5%). For MOS on TTS, our method with 100 paired data cannot generate a meaningful voice. The corresponding PER is also as high as 64.2%. When gradually adding more paired data, our method can achieve a higher MOS.
