Speech Research Intern

Department: Hardware

Location: Santa Barbara

Req#: 5631

Sonos is currently recruiting MSc/PhD candidates for an internship on the Advanced Development Team. As the Speech Research Intern, you’ll help us re-imagine how we use voice to control our music experiences.

The team is currently involved in improving the current voice and audio solutions that can be found in Sonos iconic products like the Sonos One, Sonos Beam, and the recently launched Sonos Move.

Ideally, you will have a background in one (or more) of the following disciplines:
  • Multichannel signal processing algorithm development, e.g. beamforming, noise suppression, acoustic echo cancellation, source separation
  • Audio and speech content identification and classification, e.g. acoustic scene analysis, keyword spotting and automatic speech recognition
  • Privacy-preserving and low-footprint machine learning techniques

The duration and period of the internship are flexible (3-6 months). The location is Santa Barbara, CA. 

About You

More than a candidate that checks every box, we’re looking for people who are excited to work, learn, and grow at Sonos—no matter their background or how they identify. If that’s you, we hope you’ll apply for this role.
