We are building solutions to stop harrashment and hate speech in online voice communication. The project's goal in this state, is to take user input using the default system microphone and transcode the speech to text. After that a model (unitaryai/detoxify) is used to classify the text produced from whisper as toxic, severe_toxic, obscene, threat, insult, identity_atttack.

This project was build as project for openAI's Whisper hackathon. Our project was place 2nd by the judges out of 104 teams. We intend to continue working on it in order to implement more useful features such as Real Time Speech Recognition, Multilinguality and more

Whisper is a general-purpose speech recognition model. It is trained on a large dataset of diverse audio and is also a multi-task model that can perform multilingual speech recognition as well as speech translation and language identification.

A Transformer sequence-to-sequence model is trained on various speech processing tasks, including multilingual speech recognition, speech translation, spoken language identification, and voice activity detection. All of these tasks are jointly represented as a sequence of tokens to be predicted by the decoder, allowing for a single model to replace many different stages of a traditional speech processing pipeline. The multitask training format uses a set of special tokens that serve as task specifiers or classification targets.

There are five model sizes, four with English-only versions, offering speed and accuracy tradeoffs. Below are the names of the available models and their approximate memory requirements and relative speed.

For English-only applications, the .en models tend to perform better, especially for the tiny.en and base.en models. We observed that the difference becomes less significant for the small.en and medium.en models.
