Automatic Speech Recognition (ASR)

Advanced acoustic and language modeling for superior speech-to-text accuracy.
Powered By Houndify Image
Houndify'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.

Houndify's ASR Engine

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

Improved Acoustic Modeling

Houndify'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.

Data Augmentation: Far-Field and Noisy Environments

Noisy environments present unique challenges for ASR. By augmenting our data with the unique characteristics of your user's environment, such as ambient noise, multiple speakers, and echos, we are able to deliver ASR models that operate with unprecedented accuracy.
