Word Boosting

Word Boosting (also known as Keyword/Keyterm Prompting) allows you to improve Keyword Recall Rate (KRR) for important keywords or phrases by up to 90%. This feature helps ensure accurate transcription of industry-specific terminology, product names, company names, and specialized jargon.

Enabling Word Boosting

Add keywords parameter as an array of strings in the format word:weight where weight is a positive number indicating boost intensity.

const url = new URL("wss://waves-api.smallest.ai/api/v1/pulse/get_text");

url.searchParams.append("language", "en");
3
url.searchParams.append("encoding", "linear16");
4
url.searchParams.append("sample_rate", "16000");
5
url.searchParams.append("keywords", JSON.stringify(["nacho:5.0", "bacon cheeseburger:4.0"]));

});

Case Sensitivity and Formatting

Keywords preserve formatting (including case and punctuation) which helps control how proper nouns, product names, or company names are transcribed.

Best practices for keyword formatting:

• For proper nouns (names, brands, titles): Use appropriate capitalization (Waves, iPhone, Dr. Smith)
• For non-proper nouns: Use lowercase (tretinoin, algorithm, protocol)

When smart formatting is applied to the transcript, words that start sentences may be automatically capitalized regardless of keyword formatting.

Expected Improvements

Word Boosting can significantly improve recognition accuracy and confidence scores for industry-specific terminology. Typical improvements include:
