# DisfluencySpeech Dataset

The DisfluencySpeech Dataset is a single-speaker studio-quality labeled English speech dataset with paralanguage. 
A single speaker recreates nearly 10 hours of expressive utterances from the Switchboard-1 Telephone Speech Corpus 
(Switchboard), simulating realistic informal conversations. To aid the development of a text-to-speech (TTS) model that is able to 
predictively synthesise paralanguage from text without such components, we provide three different transcripts at 
different levels of information removal (removal of non-speech events, removal of non-sentence elements, 
and removal of false starts).

Benchmark TTS models for each transcript can be found here.

# Dataset Details

All audio files are provided as 22,050 hz _.wav_ files. In the _metadata.csv_ file, 4 different transcripts for each file are provided, 
each at differing levels of information removal:

- _transcript_annotated_ is a full transcript retaining all non-speech event and disfluency annotations;
- _transcript_a_ contains all textual content recorded, including non-sentence elements and restarts. Only non-speech events such as laughter and sighs are removed from transcript;
- _transcript_b_ is _transcript_a_ but with filled pauses, explicit editing terms, and discourse markers removed. Coordinating conjunctions and asides are left in, as they are non-sentence elements as well, they are often used to convey meaning; and
- _transcript_c_ is _transcript_b_ but with false starts removed. This is the most minimal transcript.

The training set contains 90% of the data, the validation set contains 5% of the data, and the test set contains 5% of the data.
