Full Custom Language and Acoustic Modeling

In "Full" custom language and acoustic modelling, the same custom language modeling process is supplemented with the creation of a custom acoustic model that is specifically attuned to the customer's call acoustics. This dual process results in higher immunity from noise and better recognition of accents that occur commonly on the specific customer's calls. A minimum of 1000 hours of speech audio is required, and up to 25,000 hours can be used to create the models. Between 4 and 6 months are required for full custom language and acoustic model creation no matter how much audio in that range is submitted. This is the greatest amount of effort of all tuning options, but it provides the most accurate transcripts.
