WinterLight Labs (<a href=") | Machine Learning Engineer | Toronto, Canada | Full Time | Onsite &amp; At home
WinterLight Labs is a Toronto-based company which has developed cutting-edge software for objectively measuring cognitive impairment by automatically quantifying hundreds of aspects of speech and language using natural language processing algorithms and machine learning.
We are seeking a Machine Learning Engineer ​to specialize in the development of automatic speech recognition (ASR) and machine learning (ML) models. This role may involve:
● In-house implementation of state-of-the-art ASR models, using deep neural networks and open-source tools, such as Kaldi.
● Research and development of methods for online re-training and adaptation of ASR models, especially for individuals with speech disorders (e.g., aphasia) and elderly voices
● Analysis of the robustness of lexico-syntactic features derived from errorful ASR transcripts.
● Implementation of additional lexico-syntactic, semantic, and pragmatic features derived from textual transcripts
● Implementation of additional acoustic features derived from the speech signal
● Optimization of feature selection and dimensionality reduction techniques
● Optimization of model hyperparameters, and experimentation with a variety of model types.
● Optimization of multi-view approaches to data fusion
● Leveraging unsupervised and supervised approaches to data fusion
