Xenophones: An investigation of phone set expansion in Swedish and implications for speech recognition and speech synthesis

摘要

in recent years, both automatic speech recognition (ASR) and text-to-speech (TTS) conversion systems have attained quality levels that allow inclusion in everyday applications. One remaining problem to be solved in both these types of applications is that alleged phone inventories of specific languages are commonly expanded with phones from other languages, a problem that becomes more acute in a increasingly internationalized world where multilingual automatic speech-based services are a desideratum.
