Upload custom hotwords in the Intelligent Speech Interaction console and apply them to a project to improve recognition accuracy for person names, place names, and business-specific terms.
Prerequisites
Activate Intelligent Speech Interaction and create a project. For instructions, see Quick start.
Hotword categories
Hotwords have the following two categories. Each category supports up to 10 groups. Person names and place names share the name-based quota.
Name-based: Person names or place names. A hotword file can contain person names or place names, but not both.
Business-specific: Terms specific to a business domain. A file can contain different types of terms, such as Apple, Husky, and Xiaoming.

Put one hotword on each line. Chinese terms and English words or phrases are supported.
