Communication is the key to information exchange and plays an important role in people’s daily life. Modern communication technologies, such as telephone calls, video chats, and social media software or streaming websites, dominate how we communicate with each other. Behind all the technologies, one essential component is coding, which makes the transmission of information more convenient and faster.

Are you interested in artificial intelligence and human-to-human/machine communication? Would you like to apply machine learning-based methods to improve our way of daily communication? We can find a close topic for you depending on your interests.

We focus on the coding of speech and audio signals. By taking advantage of the effectiveness of deep neural networks, a coding pipeline that optimizes the traditional coding methods is being built to give better quality after coding. In this work, possible topics are as follows:
- Networks that can synthesize high-quality speech signals would be studied
- Ablation study on how to improve the performance would be carried out
- Model efficiency
- ...

Successful attendance of the lectures ‘Mustererkennung’ and ‘Sprachkommunikation’ would be desirable but not necessary.
