-
-## Intended use
-
-Speech-to-Text for the [English Language](https://en.wikipedia.org/wiki/English_language) on 16kHz, mono-channel audio.
-
-## Performance Factors
-
-Factors relevant to Speech-to-Text performance include but are not limited to speaker demographics, recording quality, and background noise. Read more about STT performance factors [here](https://stt.readthedocs.io/en/latest/DEPLOYMENT.html#how-will-a-model-perform-on-my-data).
-
-## Metrics
-
-STT models are usually evaluated in terms of their transcription accuracy, deployment Real-Time Factor, and model size on disk.
-
-#### Transcription Accuracy
-
-Using the language model with settings `lm_alpha=0.49506138236732433` and `lm_beta=0.11939819449850608` (found via `lm_optimizer.py`):
-
-- Librispeech clean: WER: 5.2\%, CER: 1.9\%
-- Librispeech clean: WER: 15.0\%, CER: 7.3\%
-- Common Voice 7.0 (Coqui custom splits): 44.4\%, CER: 24.7\%
-
-#### Model Size
-
-For STT, you always must deploy an acoustic model, and it is often the case you also will want to deploy an application-specific language model.
-
-|Model type|Vocabulary|Filename|Size|
-----------------|-----|----------------|-----|
-|Acoustic model | open | `model.tflite` | 181M|
-|Language model | large  | `large-vocabulary.scorer` |127M|
-
-### Approaches to uncertainty and variability
-
-Confidence scores and multiple paths from the decoding beam can be used to measure model uncertainty and provide multiple, variable transcripts for any processed audio.
-
-## Training data
-
-This model was trained on the following corpora: Common Voice 7.0 English (custom Coqui train/dev/test splits), LibriSpeech, and Multilingual Librispeech. In total approximately ~47,000 hours of data.
-
-## Evaluation data
-
-The validation ("dev") sets came from CV, Librispeech, and MLS.
-
-## Ethical considerations
-
-Deploying a Speech-to-Text model into any production setting has ethical implications. You should consider these implications before use.
-
-### Demographic Bias
-
-You should assume every machine learning model has demographic bias unless proven otherwise. For STT models, it is often the case that transcription accuracy is better for men than it is for women. If you are using this model in production, you should acknowledge this as a potential issue.
-
-### Surveillance
-
-Speech-to-Text may be mis-used to invade the privacy of others by recording and mining information from private conversations. This kind of individual privacy is protected by law in may countries. You should not assume consent to record and analyze private speech.
-
-## Caveats and recommendations
-
-Machine learning models (like this STT model) perform best on data that is similar to the data on which they were trained. Read about what to expect from an STT model with regard to your data [here](https://stt.readthedocs.io/en/latest/DEPLOYMENT.html#how-will-a-model-perform-on-my-data). 
-
-In most applications, it is recommended that you [train your own language model](https://stt.readthedocs.io/en/latest/LANGUAGE_MODEL.html) to improve transcription accuracy on your speech data.
