Model Overview When deployed, the ASR engine can optionally condition the transcript output on n-gram language models.
These models are simple n-gram language models trained with Kneser-Ney smoothing using KenLM.
Primary use case intended for these models is automatic speech recognition.
Input Sequence of zero or more words.
Output Likelihood of word sequence.
There are a variety of formats contained within this model archive:
ARPA-formatted Language Models:
KenLM-formatted Binary Language Models
ARPA and KenLM binary formatted files can be used directly by the CTC CPU Decoder.
To train custom LMs for ASR inference, use KenLM and consult the Riva Documentation.
By downloading and using the models, you would be accepting the terms of the Riva license.
NVIDIA’s platforms and application frameworks enable developers to build a wide array of AI applications. Consider potential algorithmic bias when choosing or creating the models being deployed. Work with the model’s developer to ensure that it meets the requirements for the relevant industry and use case; that the necessary instruction and documentation are provided to understand error rates, confidence intervals, and results; and that the model is being used under the conditions and in the manner intended.
