  # SPGISpeech
  
  SPGISpeech consists of 5,000 hours of recorded company earnings calls and their respective 
  transcriptions. The original calls were split into slices ranging from 5 to 15 seconds in 
  length to allow easy training for speech recognition systems. Calls represent a broad 
  cross-section of international business English; SPGISpeech contains approximately 50,000 
  speakers, one of the largest numbers of any speech corpus, and offers a variety of L1 and 
  L2 English accents. The format of each WAV file is single channel, 16kHz, 16 bit audio.
  
  Transcription text represents the output of several stages of manual post-processing. 
  As such, the text contains polished English orthography following a detailed style guide, 
  including proper casing, punctuation, and denormalized non-standard words such as numbers 
  and acronyms, making SPGISpeech suited for training fully formatted end-to-end models.
