With the rapid development of AI technology, datasets has become a core factor of improving intelligent system’s performance. The variety and accuracy of datasets determine the learning ability and execution effect of AI models. In the progress of training intelligent system, large amount of datasets from real world are indispensable resources. Collecting and labeling data scientifically can help AI models gain accurate results in real applications, reduce the rate of misjudgment, and improve user experience and system efficiency.

From map navigation, voice assistant, news reading, to smart customer service, call centers, and broadcast in public, the application of TTS is everywhere in our life.

Apart from text-to-speech, the research scope of speech synthesis technology also includes: singing synthesis, whisper synthesis, dialect synthesis, animal sound synthesis, and etc. At present, speech synthesis technology has been successfully applied in many fields.

Different from the traditional TTS broadcast synthesis, personalized TTS application are becoming more and more popular. Based on massive speech and text data annotation experience, Nexdata provides high-quality, multi-scenario, and multi-category speech synthesis data solutions.
