Large Vocabulary with Accuracy

Our highly optimized, tunable, and scalable ASR engine supports vocabulary sizes containing millions of words. SoundHound’s machine learning infrastructure allows us to tune the engine to achieve optimal CPU performance, while delivering higher accuracy rates.

Our deep learning architecture uses sophisticated training methods in a variety of real-world scenarios—including different acoustic conditions, speaker variations, and application domains—for the highest accuracy.

Neural Network Language models integrated with elements of NLU allow our ASR to understand the context of the spoken word and deliver higher-quality statistical models in the presence of compound sentences—resulting in increased transcription accuracy.

Dynamically augment your ASR client to accurately understand your unique lexicon and deliver more accurate results. Simply upload grammars containing new phrases and vocabularies for instant augmentation.
