<div><p><b>Abstract:</b>
We propose <i>Cotatron</i>, a transcription-guided speech encoder for speaker-independent linguistic representation.
Cotatron is based on the multispeaker TTS architecture and can be trained with conventional TTS datasets.
We train a voice conversion system to reconstruct speech with Cotatron features,
which is similar to the previous methods based on Phonetic Posteriorgram (PPG).
By training and evaluating our system with 108 speakers from the VCTK dataset,
we outperform the previous method in terms of both naturalness and speaker similarity.
Our system can also convert speech from speakers that are unseen during training,
and utilize ASR to automate the transcription with minimal reduction of the performance.
Audio samples are available at <a href="https://mindslab-ai.github.io/cotatron/#">https://mindslab-ai.github.io/cotatron</a>,
and the code with a pre-trained model will be made available soon.
</p></div>
<p>This page contains a set of audio samples in support of the paper: it is suggested that the reader listen to the samples in conjunction with reading the paper. </br>
<b>All utterances were unseen during training, and the results are uncurated (NOT cherry-picked) unless specified.</b></p>

<p>
The following audio samples are conversion between randomly selected speech from VCTK test split, which consists of 108 English speakers.
Please keep in mind that:
<ul>
<li>Our Cotatron uses transcription; where Blow doesn't.</li>
<li>The sampling rate of audios from Blow (16kHz) and Cotatron (22.05kHz) differs.</li>
</ul>
