Job summary

Apple in Cupertino, California is seeking a Speech Processing ML Algorithm Engineer to advance acoustic models for speech enhancement within the Acoustics ML Algorithm Development team.

You will design, train, and evaluate models for noise suppression and low-latency multi-microphone processing, collaborating with cross-functional teams to move prototypes into production on shipping hardware.

Qualifications

• MS or PhD in a computational science field or 3+ years of ML for speech processing.
• A passion for audio ML research for applied product applications, with a deep understanding of transformers, recurrent and convolutional neural networks.
• Experience designing, training, and evaluating machine learning models for speech enhancement, such as noise suppression, dereverberation, source separation, or echo residual suppression.
• Experience building models that meet low-latency, real-time requirements, including streaming and causal processing, and a clear understanding of the quality, complexity, and latency trade-offs involved.
• Strong grounding in audio and speech signal processing fundamentals, for example STFT analysis/synthesis.
• Proficiency with PyTorch and Bash, including version control, code review, testing, and reproducible experiments.
• A habit of following the state of the art literature closely, with the ability to reproduce, criticize, and build on published results.
• Working knowledge of speech quality evaluation, spanning objective metrics (e.g. PESQ, STOI, SI-SDR, DNSMOS) and subjective listening tests, along with the data simulation and augmentation needed to support them.

Responsibilities

• Design, train, and evaluate models for speech enhancement under low-latency, real-time constraints.
• Collaborate with cross-functional teams to bring early prototypes through to production on shipping hardware.
• Explore and reproduce published results and contribute improvements to acoustic ML methods.
