Currently, big technology companies like IBM and Amazon have good Text-to-Speech (TTS) services, APIs for production, but not Vietnamese. Google has TTS in Vietnamese in Google Translate without API. In Vietnam there are also some universities and research groups that offer TTS services such as VAIS AILAB The quality of the reading is quite good, but only at the demo level, the ability to use in production has not been proven.

Therefore, FPT Speech Synthesis(FSS) can be considered as the best Vietnamese voice synthesis service available now which owns many features, voices, continuous improvement and open APIs for the community. Built on Amazon’s AWS platform, FSS is ready to meet all production needs.
