speech2speech 0.3.0

Source lang speech to machine translation to target lang speech

Speech2Speech

The Speech2Speech Python package is a Streamlit Web application that models all phases of speech-to-speech translation, including:

• recording speech in the source language,
• converting the source language speech to source language text,
• translating the source language text to target language text, and
• converting the translated text to speech in the target language.

As a web application, it can be accessed through any web browser and is compatible with Linux, Mac, and Windows operating systems.

Speech2Speech is currently configured to translate to and from 13 different languages. Although the quality of translation may vary depending on the target language, it is pretty good for popular languages such as English, French, Portuguese, Spanish, German, Dutch and Italian. Speech2Speech can be configured for many more than just these languages (specified in the config. ini file), as long as they are supported by Whisper AI, Chat-GPT and gtts, the packages on which it depends.

Speech2Speech is designed to be accessible to a broad audience. One of the key advantages of Speech2Speech is that it's incredibly easy to use:

• The package automatically detects the source language used in speech. The user therefore is not asked to specify it.
• There is no need to train the software or the user before actually using the product. It works well straight out of the box with no further tuning or configuration required. This makes it a highly accessible tool that anyone can use, regardless of their technical expertise or experience with speech recognition and machine translation technology.

It is also hoped that this technology could be leveraged to develop products specifically designed for persons with visual impairments. It can empower them to have texts read aloud or dictate their texts and listen to them being read out loud before forwarding them to their intended recipients.

Each phase of the workflow creates a file, whose name is defined in the config.ini file. Advanced users can start and/or interrupt the workflow wherever they need by inserting their own files in the speech2speech/data subdirectory and adapting the config.ini file to refer to them.

Prerequisites

You need to get an OpenAI API key in order to use this app.

Speech2Speech local installation

Run the following command:

pip install speech2speech

In order to launch it locally follow these steps:

1. Make sure the microphone and speakers of your device are on.

2. Navigate to the directory where your Speech2Speech program is located using the cd command.

3. Type the following command in the terminal to launch Speech2Speech:

   streamlit run speech2speech.py

Workflow

Here's a step-by-step guide on how to use the full workflow of Speech2Speech:

1. Copy your OpenAI API key and paste it into the text box below the label "OpenAI API Key". The API key you enter will not be visible on the screen by default.
2. Click the "Record Audio" button to start recording.
3. Begin speaking or reading aloud. When your dictation is finished, press CTRL+E to stop recording it. Chat-GPT can automatically detect the language you're speaking (as long as it also supports it), so there's no need to specify it.
4. Click the "Transcribe" button to convert your dictation into text.
5. Select your desired target language from the dropdown menu under "Target Language".
6. Click the "Translate" button to translate the transcription into your chosen target language. The translated text will appear on a blue background after a few seconds.
7. Click the "Read Translation" button to listen to the translated text.
8. If you want to repeat the process with a new dictation, click the "Refresh Page" button to reset the page.

As indicated above, you can also use just parts of this full workflow by specifying the name(s) of the file(s) you want to use in the config.ini file and by clicking the relevant button of the user interface.

What to do if you encounter issues

If Chat-GPT or Speech2Speech get stuck or you encounter any issues, simply refresh the browser page. ChatGPT may, however, have lots of users at certain times of the day and be poorly responsive for a while.
