The development of Modern AI, not only relies on complex algorithms and calculate abilities, but also requires a massive amount of real and accurate data as support. For companies and research institutes, having high-quality datasets means gaining an advantage in technology innovation competitiveness. As increasingly demanding of AI model’s accuracy and generalization, specialized data collection and annotation work has becomes indispensable.

In 2022, the trend of AIGC is sweeping the world, multiple AI fields are developing rapidly, painting, music, news creation, anchor and many other industries are being redefined, and the Metaverse is becoming more and more popular.

On December 16, 2022, Science magazine released the top ten breakthroughs in science in 2022, and AIGC is on the list. Gartner predicts that AIGC will account for 10% of all data generated by 2025. Generative AI: According to ACreative New World analysis, AIGC has the potential to generate trillions of dollars in economic value.

Under the wave of AIGC, the output of AIGC content based on speech synthesis technology has also developed rapidly. From the concatenated speech synthesis technology used by Hawking, to parameter synthesis, and now to the neural network-based parameter management system. TTS is developing very rapidly around the world. The speech synthesizer WaveNet created by DeepMind has greatly improved the sound quality of speech synthesis.

Audio generation can be divided into TTS (Text-to-speech) scene and music generation. Among them, TTS includes voice customer service, audiobook production, intelligent dubbing and other functions. Generating a musical composition includes generating a specific musical composition based on opening melody, pictures, text descriptions, music genres, emotional genres, and the like.

Microsoft’s intelligent speech technology has been upgraded again, and it has realized the support of multiple dialects in speech synthesis. Recently, Microsoft announced that it has implemented support for two Chinese dialects, Wu Dialect and Cantonese Dialect, as well as Southwest Mandarin, Northeast Mandarin, Jilu Mandarin, and Central Plains Mandarin (including Henan and Shaanxi) in speech synthesis.

Large volume and high-quality training data is the foundation of speech synthesis technology. Nexdata provides customers with multi-timbral, multi-language, high-quality training data based on massive voice and text data annotation experience and leading speech synthesis technology.
