Keywords are a way of specifying that certain words are expected to appear in a conversation, which can help increase the accuracy of speech recognition models without having to train them on all possible audio scenarios and special vocabulary. Deepgram's deep learning platform utilizes keyword information to make more accurate predictions. Customers who want better performance on product names or industry-specific vocabulary can use keywords to increase the chances that Deepgram's model will predict those words instead of more common ones. Keyword boosting is useful for improving speech recognition accuracy in specific contexts, but a custom model trained on representative data will always give the best performance.
