Improve transcription accuracy with hinting
Voci’s speech-to-text engine provides high levels of accuracy with no customization. From this strong baseline, it is possible to improve accuracy further by tuning the ASR to better understand each enterprise's specific call interactions with its customers. Voci Labs is developing a hinting solution to help drive the tuning process.
A “hint” is an important word or short phrase that you expect to be used frequently in a specific call or set of calls, such as the names of brands, products, companies, people, and phone numbers specific to the call environment. Because those words do not occur together with high frequency in general speech, Voci's off-the-shelf language models consider such word pairings to be unlikely. Without hinting, these phrases will be transcribed at lower accuracy than the rest of the conversation.
Hinting is an effective method for improving the accuracy of targeted phrases, such as those directly impacting categorization. Hinting is also useful for correcting frequently occurring phrases with unusual word groupings, such as those found in marketing slogans, disclaimers, and required legal statements.
