Job Description

Targeted speech hearing in a multi-source auditory environment is crucial for the latest hearing acoustics applications such as ear buds, hearing aids, smart watches, in-car acoustics, etc. In the latest hearing devices, AI-based systems such as recurrent neural networks, LSTMs, beamformer networks are deployed to perform noise cancellation, speaker enhancement, etc. With the introduction of directives, target speaker identification is possible without the need for clean target samples.

• During your Master thesis, you investigate target speech extraction with different background noises and develop a target extraction method based on directives. You will evaluate speech extraction methods for hearing aids.
• You will perform data augmentation on toy datasets and implement pre-processing stages of audio.
• Furthermore, you develop neural networks to extract target speech based on directives.
• In addition, you extend the developed method to multi-source speech targets.
• Last but not least, you will gain experience and collaborate in a cross-functional team spanning algorithms, deployment and hardware.

Qualifications

• Education: Master studies in the field of Electrical Engineering, Computer Science or comparable
• Experience and Knowledge in Python and C++; background in Neural Networks; knowledge of PyTorch is an advantage
• Personality and Working Practice: anindependent, structured and highly motivated person
• Enthusiasm: keen interest in future technologies and trends with a passion for innovation
• Languages: fluent in English, German is an advantage
