Chip

In 2016, Chipintelli launched the industry's first AI voice chip CI1006, and has since introduced over 20 models of AI voice chips, establishing a comprehensive product matrix. These chips feature high speech recognition rates, strong noise resistance, and on-device large language models. They support multiple languages including Chinese, English, Japanese, Korean, Southeast Asian languages, Arabic, European languages, and regional dialects like Cantonese. They provide high-performance, reliable, low-power, and cost-effective on-device intelligent voice solutions for both domestic and international users.
