-If you select the [Neural](?tabs=neural) training type, you can train a voice to speak in multiple languages. The `zh-CN` and `zh-TW` locales both support bilingual training for the voice to speak both Chinese and English. Depending in part on your training data, the synthesized voice can speak English with an English native accent or English with the same accent as the training data.
