يُعد LibriTTS-R نسخةً محسّنة من جودة الصوت لمجموعة بيانات LibriTTS، وقد نُشر البحث المتعلق بها في الورقة العلمية بعنوان LibriTTS-R: A Restored Multi-Speaker Text-to-Speech Corpus، بهدف توفير بيانات صوتية إنجليزية عالية الجودة لأبحاث النطق الاصطناعي.

تحتوي هذه المجموعة على حوالي 585 ساعة من تسجيلات القراءة باللغة الإنجليزية لمتحدثين متعددين، بمعدل عينة يبلغ 24 كيلوهرتز، ومقسمة إلى سبع شرائح بيانات (_splits).

                   ``LibriTTS-R'' designed for text-to-speech (TTS) use. It is
                   derived by applying speech restoration to the LibriTTS
                   corpus, which consists of 585 hours of speech data at 24 kHz
                   sampling rate from 2,456 speakers and the corresponding
                   texts. The constituent samples of LibriTTS-R are identical
                   to those of LibriTTS, with only the sound quality improved.
                   Experimental results show that the LibriTTS-R ground-truth
                   samples showed significantly improved sound quality compared
                   to those in LibriTTS. In addition, neural end-to-end TTS
                   trained with LibriTTS-R achieved speech naturalness on par
                   with that of the ground-truth samples. The corpus is freely
                   available for download from
