HERE WeGo relies on your smartphone's Operating System (Android or iOS) capabilities to produce voice commands.
It means that a text-to-speech (TTS) engine of your smartphone should be enabled and configured for WeGo to produce voice commands for navigation. This also includes languages the TTS engine supports: please make sure that the desired language pack is loaded in your system TTS. Usually, text-to-speech systems offer a variety of voices and settings (male/female, low/high pitch, speed of narration), so please set it up for your convenience using your smartphone's system settings. Please note that available settings depend on the smartphone model and operating system.
If a language you need is not supported by the TTS engine in use, you can try and install external TTS engines from app stores or their vendors' site.
