# Earnings 22
The Earnings 22 dataset ( also referred to as earnings22 ) is a 119-hour corpus of English-language earnings calls collected from global companies. The primary purpose is to serve as a benchmark for industrial and academic automatic speech recognition (ASR) models on real-world accented speech.
This work has been submitted for publication at Interspeech 2022.

# File Format Overview
In the following section, we provide an overview of the file formats we provide with this dataset.
## nlp Files
NLP files are `.csv` inspired, pipe-separated text files that contain token and metadata information of a transcript. Each line of a file represents a single transcript token and the metadata associated with it.
|Column Title|Description
|--|--|
| Column 1: `token` | A single token in the transcript. These are typically single words or multiple words with hyphens in between. |
| Column 2: `speaker` | A unique integer that associates this token to a specific speaker in an audio |
Column 3: `ts` | A float representing the start time of the token, in seconds |
Column 4: `endTs` | A float representing the end time of the token, in seconds |
Column 5: `punctuation` | A punctuation character that is included at the end of a token that is used when reconstructing the transcript. Example punctuation: `",", ";", ".", "!"`. |
Column 6: `case` | A two letter code to denominate the which of four possible casings for this token:
- `UC` - Denotes a token that has the first character in uppercase and every other character lowercase.
- `LC` - Denotes a token that has every character in lowercase.
- `CA` - Denotes a token that has every character in uppercase.
- `MC` - Denotes a token that doesn’t follow the previous rules. This is the case when upper- and lowercase characters are mixed throughout the token
|
Column 7: `tags` | Displays one of the several entity tags that are listed in wer_tags in long form - such that the displayed entity here is in the form `ID:ENTITY_CLASS`. |
Column 8: `wer_tags` | A list of entity tags that are associated with this token. In this field, only entity IDs should be present. The specific ENTITY_CLASS for each ID can be extracted from an accompanying wer_tags sidecar json. |
_**Note that each entity ID is unique to that specific entity. Entities can be comprised of single and multiple tokens. Within a file there can be several entities of the same ENTITY_CLASS but only one entity can be labeled with any given ID.**_

# Results
Tables found in the paper along with all entity class WER can be found within the `transcripts` directory.
# WER Calculation
All of our analysis on this dataset is done through the use of our newly released [fstalign](https://github.com/revdotcom/fstalign/tree/master) tool. We strongly recommend the use of this tool to quickly get started using the *Earnings-22* dataset.
