# The TORGO Database: Acoustic and articulatory speech from speakers with dysarthria
## Dataset Summary
- This database only includes the short words and restricted sentence portion of the TORGO dataset.
- For the full dataset which also includes non-words and unrestricted sentences please see: https://www.cs.toronto.edu/~complingweb/data/TORGO/torgo.html.
- Transcripts have been normalized to remove punctuation but casing has been left. Few transcripts only had 'xxx' as text, these were removed.
- About 5.5 hours of dysarthric speech data and 8 hours of healthy speech.


<b>Short words</b><br>
These are useful for studying speech acoustics without the need for word boundary detection. This category includes the following:
- Repetitions of the English digits, 'yes', 'no', 'up', 'down', 'left', 'right', 'forward', 'back', 'select', 'menu', and the international radio alphabet (e.g., 'alpha', 'bravo', 'charlie'). These words are useful for hypothetical command software for accessibility.
- 50 words from the the word intelligibility section of the Frenchay Dysarthria Assessment (Enderby, 1983).
- 360 words from the word intelligibility section of the Yorkston-Beukelman Assessment of Intelligibility of Dysarthric Speech (Yorkston and Beukelman, 1981).
- The 10 most common words in the British National Corpus.

<b>Restricted sentences</b><br>
In order to utilize lexical, syntactic, and semantic processing in ASR, full and syntactically correct sentences are recorded. These include the following:
- Preselected phoneme-rich sentences such as "The quick brown fox jumps over the lazy dog", "She had your dark suit in greasy wash water all year", and "Don't ask me to carry an oily rag like that."
- The Grandfather passage.
- 162 sentences from the sentence intelligibility section of the Yorkston-Beukelman Assessment of Intelligibility of Dysarthric Speech (Yorkston and Beukelman, 1981).
- The 460 TIMIT-derived sentences used as prompts in the MOCHA-TIMIT database (Wrench, 1999; Zue et al, 1989).



## Dataset Structure
- Data points comprise the path to the audio file and its transcription.
- Additional fields include gender, speech status (dysarthria or healthy), and duration
- No dev/test split is provided as there is no standard split for this dataset.
- Filenames are as follows:
  - speakerNumber_sessionNumber_micType_utteranceNumber.wav
    - Speaker number has the format of gender-speechStatus-speakerNumber (e.g. FC01 = Female control #1, M04 = Male dysarthric #4)
