Custom train/dev/test splits are created by [Common Voice Corpora Creator](https://github.com/common-voice/CorporaCreator) with --duplicate-sentence-count 99 parameter, which allowed us to use the whole dataset. The dataset contains approximately ~11 hours of voice data (276 distinct voices, 65% male, 4% female). + +Note: Our model numbering for Common Voice only data reflect Common Voice corpus version and Corpora Creator duplicate-sentence-count (dsc) setting (e.g. "v0.corpus.dsc"). + +## Evaluation data + +The validation ("dev") and test ("test") sets also came from CV as specified above. + +## 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. diff --git a/hindi/bozden/v0.8.99/alphabet.txt b/hindi/bozden/v0.8.99/alphabet.txt new file mode 100644 index 0000000..96ec0a4 --- /dev/null +++ b/hindi/bozden/v0.8.99/alphabet.txt @@ -0,0 +1,76 @@ +# Each line in this file represents the Unicode codepoint (UTF-8 encoded) +# associated with a numeric index. +# A line that starts with # is a comment.
