# CustomClass

CustomClass in Google Cloud is a Speech-to-Text resource that defines custom word classes to improve recognition accuracy for specific terms, such as product names or domain-specific vocabulary. It allows users to group related words or phrases and reference them in speech adaptation configurations, helping the model better understand context and pronunciation variations.
