Voice recognition may provide a low recognition accuracy for place names, product names, company names, and specialized vocabulary in a certain field, such as brand name Zhi Ling, building name Empire State Building, technology name Redis, insurance vocabulary underwriting, cloud storage vocabulary bucket, original food name JJ Pizza, etc. For these specialized words, we provide the boosted word feature for users, which can significantly improve the recognition accuracy of these specialized words by adding boosted words.
Usage Recommendations
Common words are not recommended to be added to boosted keywords , for example, "customer", "friend", and other words. Adding too many common words will reduce the recognition rate of specialized words.
The greater the weight of boosted keywords, the greater the probability of being recognized. Boosted keyword weight is an integer between [1,10].
Adding boosted keywords can greatly improve recognition accuracy and is one of the important ways to quickly improve specialized vocabulary. However, there may still be a probability that it cannot be correctly recognized. In this case, first confirm whether the clarity and quality of the audio meets the standard, and the standard is that a layman can correctly recognize the text after listening to the recording once.
