Q1:How many languages are supported?
A1:22 countries in total. English, Chinese, Korean, Japanese, German, French, Spanish, Portuguese, Dutch, Italian, Thai, Vietnamese, Indonesian, Hindi, Telugu, Malayalam, Bengali, Arabic, Urdu, Russian, Ukrainian, and Hebrew.
Q2:What is the translation accuracy?
A2:It depends on the language, but there are other factors that affect accuracy, such as noise in the original voice at the transcript stage or ambient noise that makes it difficult to hear. On the other hand, if the GPU environment can be detected automatically, we switch to the model with the highest accuracy.
Q3:What is the real-time performance?
A3:Unfortunately, perfect simultaneous interpretation is difficult due to the nature of language grammar, but the PVT series uses 3 seconds as a standard, and by adding functions such as silence detection, translations are made in units of one phrase or one sentence as much as possible. The average delay is 1 or 2 sentences. The translation speed is about the level of “a little slow? Please be aware that there may be further delays depending on the network environment.
Q4:Will the conversation be leaked to outside parties?
A4:Basically, voice data is processed inside the PC, so it will not be leaked on the network. However, the transcribed text data will go through the network in order to use Google Translate. Please avoid conversations involving sensitive information. Also, we cannot guarantee opt-out.
Q5:How long can I use the trial version?
A5:15 days after installation and first execution.
Q6:How long can I use the commercial version?
A6:Basically, it is valid until the end of July 2030. The reason for this is that development in this field is very fast and performance and specifications change significantly, which may affect compatibility. We have taken the liberty of setting an expiration date of approximately 5 years after release. The trial version will be available until the end of July 2030 as well.
Q7:Where can I obtain the GPU environment?
A7:The PVT series supports CUDA; please register as a user separately from the NVIDIA website and install CUDA. CUDA Toolkit 12.x and cuDNN 9.6.x are recommended.
However, a full CUDA environment is not required; the PVT series will automatically install and run the appropriate CUDA libraries if NVIDIA GPU drivers are installed at a minimum. (Existing CUDA environments will not be affected, but older drivers may cause some instability. It is recommended to update to the latest drivers.)
How to check the driver:
Open a command prompt and execute “nvidia-smi”. If the driver Version is displayed, it is OK.
Example: C:\Users\<user name>\nvidia-smi
Reference: CUDA Toolkit Archive | NVIDIA Developer
Q8:How can I force the display of the translation language selection field to English?
A8:Open the file C:\Users\<user name>\AppData\Local\PVTleaf\user_env\environment.json and edit it as follows. After that, restart PetitVoiceTranslator_Leaf and you will see the English menu.
