Resolvity Awarded U.S. Patent for ASR Technology

Resolvity has been awarded a U.S. patent for a method and system for grammar relaxation for automated speech recognition (ASR) systems. ASR systems take spoken utterances as input and use grammars to assign word sequences and interpretation of the utterances.

"This method automatically modifies grammars by adding new grammar components or reducing the importance of existing grammar components based on the analysis of the occurrence of these components in the original grammar," said Jacek Jarmulak, Resolvity’s senior scientist and an inventor of the method, in a statement. "It is particularly powerful when concepts being recognized are organized into a hierarchy."

Resolvity automates several million calls every month for Fortune 1000 companies in the U.S. using its cloud-based speech recognition interactive voice response (IVR) system.

"The invention reduces the effort required for building grammars, improves recognition accuracy, and enables the automatic adaptation of dynamic grammars to the context of each interaction," said Mahesh Rajagopalan, co-founder and president of Resolvity, in a statement. "Our clients have already achieved lower operating costs and improved performance in their speech recognition-based interactive voice response systems using this method."
