   Sammanfattning : This dissertation investigates linguistic and metalinguistic practices in everyday Twitter discourse in relation to aspects of speech and writing. The overarching aim is to investigate how the spoken–written interface is reconfigured in the digital writing spaces of social media. LÄS MER

3. 2. Speech enhancement for mobile communications

   Författare :Harald Gustafsson; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; spectral subtraction;

   Sammanfattning : Three major applications of speech enhancement have been studied: noise reduction for mobile telephone handsfree accessories, noise reduction for handheld mobile telephones, and short delay noise reduction for frame-less telephone systems. During conversation, both hearing and speaking adapt to the background noise in a noisy environment. LÄS MER

   Sammanfattning : The aim of a text-to-speech synthesis (TTS) system is to generate a human-like speech waveform from a given input text. Current TTS sys- tems have already reached a high degree of intelligibility, and they can be readily used to read aloud a given text. For many applications, e.g. LÄS MER
