- Due to the COVID-19 pandemic, the lecture Audio Processing for the Internet of Things will be offered as a fully virtual course via ZOOM.
- Participation in the ZOOM sessions is only possible for FAU students. To access the Zoom sessions, you must register via StudOn prior to the first lecture. In StudOn, you will then find Zoom access information.
- As a technical requirement, all participants must have access to a computer capable of running the ZOOM video conferencing software, including a stable internet connection for audio and video transmission.
The course focuses on audio and speech processing algorithms within the context of the Internet of Things (IoT).
Reading material recommendations are provided during the lectures.
- Foundation: history, components, current challenges
- Overview of Relevant Wireless Protocols: bandwidth, range, latency, spectrum
- Audio Device Synchronization: NTP, PTP, device orchestration, wireless acoustic sensor networks, asynchronous and event-driven audio sampling
- Acoustic Sensing for Voice User Interfaces: keyword spotting, speech recognition, speaker verification, anti-spoofing
- Acoustic Scene Detection: event detection, scene classification, anomaly detection, sound tagging, blind reverb estimation
- Sound Creation: text-to-speech, sound generative networks
- Data-over-sound: sound-beacon, watermarking, acoustic fingerprint
- Privacy in IoT: edge vs. cloud processing, secure signal processing, federated learning, differential privacy, audio encryption
