Scale up Your AI Initiatives with High-quality Speech Recognition Dataset

From:Datatang Date:2023-03-31

According to Deloitte statistics, it is estimated that by 2030, China's smart voice consumer and enterprise application markets will exceed 70 billion Yuan and 100 billion Yuan respectively. From a global perspective, the scale of the global intelligent voice industry will reach US$35.12 billion in 2022, maintaining a high growth rate of 33.1%.

Speech recognition technology simply refers to the technology required for a machine or program to accept passwords, interpret the meaning of sounds, and understand and execute spoken instructions. In the era of intelligence, the application of smart terminals is becoming more and more popular. Correspondingly, more and more scenarios use dialogue as the main form of interaction when designing personalized human-computer interaction interfaces. And a complete dialogue interaction is a closed loop composed of three links of "input-analysis-output". Speech recognition technology is the beginning of dialogue interaction and the basis for ensuring efficient and accurate human-computer interaction.

The speech recognition decoding process includes two parts: recognition modeling and model training of the acoustic model and language model. During the running process, the amount of training data and the amount of calculation required are huge. Therefore, cloud computing technology, which can provide massive speech recognition dataset, storage and high-performance computing capabilities, has become an application hotspot in the speech recognition industry.

As a data service provider with 12+ years of data processing experience, Datatang provides multi-scenario and multi-type speech recognition dataset. Datatang has accumulated 200,000 hours of multilingual, multi-channel, multi-environment, and multi-type finished speech recognition dataset. The speech recognition dataset can help customers quickly optimize speech recognition models.
