![]() And secondly no automatic chunking is applied, which means that you cannot transcribe content that is larger than 30 seconds. First you need to manually set the source language (no automatic input language detection is implemented yet). There are 2 limitations with this Hugging Face implementation. Print(processor.batch_decode(predicted_ids, skip_special_tokens = True)) Transcription = processor.batch_decode(predicted_ids) Predicted_ids = model.generate(input_features) Input_features = processor(speech, return_tensors="pt").input_features _decoder_ids = processor.get_decoder_prompt_ids(language = "en", task = "transcribe") Model = om_pretrained("openai/whisper-large") Processor = om_pretrained("openai/whisper-large") Now, here is a Python script that does transcription in English:įrom transformers import WhisperProcessor, WhisperForConditionalGeneration You also need to install ffmpeg (see above). In order to use Hugging Face's implementation of Whisper you will first need to install HF Transfomers, librosa, and Pytorch: Here is a very simply Python script that opens an mp3 audio file stored on your disk, automatically detects the input language, and transcribes it: Of course the bigger the better, so if you are looking for state of the art results we recommend the large version. Several flavors of Whisper are available: tiny, base, small, medium, and large. Sudo apt update & sudo apt install ffmpeg Then install ffmpeg on your system if it is not the case yet: You basically need to follow OpenAI's instructions on the Github repository of the Whisper project. The first one is to use OpenAI's whisper Python library, and the second one is to use the Hugging Face Transformers implementation of Whisper. You have 2 options if you want to install and deploy Whisper for the moment. If you prefer to benefit from a managed version, you can use an API like NLP Cloud: Whisper is free of course, but if you want to install it by yourself you will need to spend some human time on it, and pay for the underlying servers and GPUs. Accuracy is very good, and you can apply this model to any kind of input (audio, video, phone calls, medical discussions, etc.).Īnd of course, another great advantage of Whisper is that you can deploy it by yourself on your own servers, which is great from a privacy standpoint. Whisper is taking the speech-to-text ecosystem by storm: it can automatically detect the input language, then transcribe text in around 100 languages, automatically punctuate the result, and even translate the result if needed. Their 2 most exciting models: GPT-3 and DALL-E, are still private models that can only be used through their paid API. Not all OpenAI's models have been open-sourced though. ![]() Recently, they also released a nice CUDA programming framework called Triton. At the time it was the best generative natural language processing model ever created, and it paved the way for much more advanced models like GPT-3, GPT-J, OPT, Bloom. For example GPT-2 was developed by OpenAI a couple of years ago. OpenAI has a history of open-sourcing great AI projects. Whisper is an open-source AI model that has just been released by OpenAI. Whisper: The Best Alternative To Google Speech-To-Text If you are concerned about costs or privacy, you might want to switch to an open-source alternative: OpenAI Whisper. If you have 5 support agents spending 4h each per day on the phone with customers, Google's speech-to-text API will cost you $1,400 per month. Let's say you want to automatically analyze phone calls made to your support team (in order to later perform sentiment analysis or entity extraction on them for example). Google's pricing is basically $0.006 / 15 seconds for basic speech-to-text, and $0.009 / 15 seconds for specific use cases like video transcription or phone transcription. But it's important to note that the on-prem AI model will keep sending data to Google in order to report API usage, which might be a concern from a privacy standpoint. Last of all, their API can be installed on premises. This API also has nice additional features like content filtering, automatic punctuation (in beta only for the moment), and speaker diarization (in beta too). This API is able to transcribe audio and video files in 125 languages, and it proposes specific AI models for phone calls transcription, medical transcription, and more. Google's automatic speech recognition (speech-to-text) API is very popular.
