Automatic Speech Recognition (ASR)

Advanced acoustic and language modeling for superior speech-to-text accuracy.
Powered By Houndify Image
SoundHound's Automatic Speech Recognition (ASR) technology delivers higher sentence accuracy through embedded meaning and a richer context for recognizing words. The integration of our Natural Language Understanding (NLU) components enables our neural network-based ASR to transcribe complex speech with greater precision.

SoundHound's ASR Engine

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.

Improved Acoustic Modeling

SoundHound's acoustic modeling architecture uses machine learning to increase word recognition accuracy. Rapid iteration is possible due to our accelerated training pipeline and architecture that improves as data is collected. Highly accurate transcriptions result from advanced acoustic models trained to perform in a variety of scenarios—including in severely noisy environments and when accented language is spoken.

"With voice, there are many more challenges because, for example, if you think about the artists Fish with “F” and with “PH”. Since we're building this hands-free experience for voice mode, when you ask for something, we can only play one result and we have just one opportunity to nail the right one for you."

Advanced Language Modeling

We've integrated Neural Network Language models and elements of NLU to allow SoundHound's ASR to understand the context of the spoken word. The result is a technology that delivers higher-quality statistical models in the presence of compound sentences, resulting in increased transcription accuracy.
