Light Language Modeling

Creating a custom language model improves overall accuracy and adds new words to the model dictionary that are specific to a customer's business. "Light" language modeling requires 50-100 hours of recorded speech audio. This audio must be transcribed manually and combined with existing language resources to create a custom language model that is better attuned to a specific customer's calls. Typically, fewer than two months are required for model creation once Voci receives recorded audio. The combined effort of audio collection and model creation is non-trivial, but once the model is deployed, transcription accuracy is improved with no negative impact on transcription speed.
