- This tool is not perfect. It's still in beta and is a work in progress. It will be updated in a reasonable amount of time. Example: The tool might occasionally provide inaccurate translations or encounter bugs that are being actively worked on by the developers.
- Translations are more accurate when the speaker speaks clearly and slowly. If the speaker is fast or unclear, the translation will be less accurate, though it will still provide some level of translation. Example: If the speaker speaks slowly and enunciates clearly, the tool is likely to provide more accurate translations compared to when the speaker speaks quickly or mumbles.
- The tool is not intended for professional use. It's meant for fun, language learning, and enjoying content at a reasonable pace. You may need to try to understand the content on your own before using this tool. Example: This tool can be used for casual conversations, language practice with friends, or enjoying audio content in different languages.
- You agree not to use the tool to produce or spread misinformation or hate speech. If there is a discrepancy between the tool's output and the speaker's words, you must conduct your own research to determine the truth. Example: If the tool translates a statement into something false or misleading, it is your responsibility to verify the accuracy of the information before sharing it. Avoid using the tool to spread false information or engage in hate speech.
- You assume your own risk and liability. The repository owner will not be held responsible for any damages caused by the tool. You are responsible for your own actions and cannot hold the repository owner accountable if you encounter issues or face consequences due to your usage of the tool. Example: If the tool encounters technical issues, fails to provide accurate translations, or if you face any negative consequences resulting from its usage, the repository owner cannot be held liable.
- The tool is not meant to replace human translators. It is designed for fun, language learning, and enjoying content at a reasonable pace. You may need to make an effort to understand the content on your own before using this tool. Example: When dealing with complex or highly specialized content, it is advisable to consult professional human translators for accurate translations.
- Your hardware can affect the tool's performance. A weak CPU or GPU may hinder its functionality. However, a weak internet connection or microphone will not significantly impact the tool. Example: If you have a powerful computer with a fast processor, the tool is likely to perform better and provide translations more efficiently compared to using it on a slower or older system.
- This is a tool, not a service. You are responsible for your own actions and cannot hold the repository owner accountable if the tool violates terms of service or end-user license agreements, or if you encounter any issues while using the tool. Example: If you use the tool in a way that violates the terms of service or policies of the platform you're using it with, the repository owner cannot be held responsible for any resulting consequences.

- You can choose any python version that is 3.10.9 up to the latest version. The tool will not work on any python version that is 3.11 or higher. Must be 3.10.9+ not 3.11.x.
- Download and install Git.
- Using default settings is fine.
- Download and install FFMPEG
- Instructions: cyberofficial#2 (comment)
- Download and install CUDA [Optional, but needs to be installed if using GPU]
- Run setup script
- On Windows:
setup.bat - On Linux:
setup.bash - If you get an error saying "Setup.bat is not recognized as an internal or external command, operable program or batch file.", houston we have a problem. This will require you to fix your operating system.
- On Windows:
- Run the newly created batch file/bash script. You can edit that file to change the settings.
- If you get an error saying it is "not recognized as an internal or external command, operable program or batch file.", make sure you have installed and added to your PATH, and make sure you have git installed. If you have python and git installed and added to your PATH, then create a new issue on the repo and I will try to help you fix the issue.
This script uses argparse to accept command line arguments. The following options are available:
| Flag | Description |
|---|---|
--ram |
Change the amount of RAM to use. Default is 4GB. Choices are "1GB", "2GB", "4GB", "6GB", "12GB". |
--ramforce |
Use this flag to force the script to use desired VRAM. May cause the script to crash if there is not enough VRAM available. |
--non_english |
Use non-English models for transcription. Enables the use of non-English models. |
--energy_threshold |
Set the energy level for microphone to detect. Default is 100. Choose from 1 to 1000; anything higher will be harder to trigger the audio detection. |
--record_timeout |
Set the time in seconds for real-time recording. Default is 2 seconds. |
--phrase_timeout |
Set the time in seconds for empty space between recordings before considering it a new line in the transcription. Default is 1 second. |
--translate |
Translate the transcriptions to English. Enables translation. |
--transcribe |
Transcribe the audio to a set target language. Target Language flag is required. |
--target_language |
Select the language to translate to. Available choices are a list of languages in ISO 639-1 format, as well as their English names. |
--language |
Select the language to translate from. Available choices are a list of languages in ISO 639-1 format, as well as their English names. |
--auto_model_swap |
Automatically swap the model based on the detected language. Enables automatic model swapping. |
--device |
Select the device to use for the model. Default is "cuda" if available. Available options are "cpu" and "cuda". When setting to CPU you can choose any RAM size as long as you have enough RAM. The CPU option is optimized for multi-threading, so if you have like 16 cores, 32 threads, you can see good results. |
--cuda_device |
Select the CUDA device to use for the model. Default is 0. |
--discord_webhook |
Set the Discord webhook to send the transcription to. |
--list_microphones |
List available microphones and exit. |
--set_microphone |
Set the default microphone to use. You can set the name or its ID number from the list. |
--auto_language_lock |
Automatically lock the language based on the detected language after 5 detections. Enables automatic language locking. Will help reduce latency. Use this flag if you are using non-English and if you do not know the current spoken language. |
--use_finetune |
Use fine-tuned model. This will increase accuracy, but will also increase latency. Additional VRAM/RAM usage is required. |
--no_log |
Makes it so only the last thing translated/transcribed is shown rather log style list. |
--retry |
Retries translations and transcription if they fail. |
--about |
Shows about the app. |
- When crafting your command line arguments, you need to make sure you adjust the energy threshold to your liking. The default is 100, but you can adjust it to your liking. The higher the number, the harder it is to trigger the audio detection. The lower the number, the easier it is to trigger the audio detection. I recommend you start with 100 and adjust it from there. I seen best results with 250-500.
- When using the discord webhook make sure the url is in quotes. Example:
--discord_webhook "https://discord.com/api/webhooks/1234567890/1234567890" - An active internet connection is required for initial usage. Over time you'll no longer need an internet connection. Changing RAM size will download certain models, once downloaded you'll no longer need internet.
- The fine tuned model will automatically be downloaded from OneDrive via Direct Public link. In the event of failure
Please note, make sure you edit the livetranslation.bat/livetranslation.bash file to change the settings. If you do not, it will use the default settings.
You have a GPU with 6GB of memory and you want to use the Japanese model. You also want to translate the transcription to English. You also want to send the transcription to a Discord channel. You also want to set the energy threshold to 300. You can run the following command:
python transcribe_audio.py --ram 6gb --non_english --translate --language ja --discord_webhook "https://discord.com/api/webhooks/1234567890/1234567890" --energy_threshold 300
When choosing ram, you can only choose 1gb, 2gb, 4gb, 6gb, 12gb. There are no in-betweens.
You have a 12gb GPU and you want to translate to Spanish from English, you can run the following command:
python transcribe_audio.py --ram 12gb --transcribe --target_language Spanish --non_english --language en
Lets say you have multiple audio devices and you want to use the one that is not the default. You can run the following command:
python transcribe_audio.py --list_microphones
This command will list all audio devices and their index. You can then use the index to set the default audio device. For example, if you want to use the second audio device, you can run the following command:
python transcribe_audio.py --set_microphone "Realtek Audio (2- High Definiti" to set the device to listen to. *Please note the quotes around the device name. This is required to prevent errors. Some names may be cut off, copy exactly what is in the quotes of the listed devices.
Example lets say I have these devices:
Microphone with name "Microsoft Sound Mapper - Input" found, the device index is 1
Microphone with name "VoiceMeeter VAIO3 Output (VB-Au" found, the device index is 2
Microphone with name "Headset (B01)" found, the device index is 3
Microphone with name "Microphone (Realtek USB2.0 Audi" found, the device index is 4
Microphone with name "Microphone (NVIDIA Broadcast)" found, the device index is 5
I would put python transcribe_audio.py --set_microphone "Microphone (Realtek USB2.0 Audi" to set the device to listen to.
-or-
I would put python transcribe_audio.py --set_microphone 4 to set the device to listen to.
If you encounter any issues with the tool, here are some common problems and their solutions:
- Python is not recognized as an internal or external command, operable program or batch file.
- Make sure you have Python installed and added to your PATH.
- If you recently installed Python, try restarting your computer to refresh the PATH environment variable.
- Check that you installed the correct version of Python required by the application. Some applications may require a specific version of Python.
- If you are still having issues, try running the command prompt as an administrator and running the installation again. However, only do this as a last resort and with caution, as running scripts as an administrator can potentially cause issues with the system.
- I get an error saying "No module named 'transformers'".
- Re-run the setup.bat file.
- If issues persist, make sure you have Python installed and added to your PATH.
- Make sure you have the
transformersmodule installed by runningpip install transformers. - If you have multiple versions of Python installed, make sure you are installing the module for the correct version by specifying the Python version when running the command, e.g.
python -m pip install transformers. - If you are still having issues, create a new issue on the repository and the developer may be able to help you fix the issue.
- Re-run the setup.bat file.
- Git is not recognized as an internal or external command, operable program or batch file.
- Make sure you have Git installed and added to your PATH.
- If you recently installed Git, try restarting your computer to refresh the PATH environment variable.
- If you are still having issues, try running the command prompt as an administrator and running the installation again. However, only do this as a last resort and with caution, as running scripts as an administrator can potentially cause issues with the system.
- CUDA is not recognized or available.
- Make sure you have CUDA installed. You can get it from here.
- CUDA is only for NVIDIA GPUs. If you have an AMD GPU, you have to use the CPU model. ROCm is not supported at this time.
