CoPilot can say the name of the roads or the exit numbers when a text-to-speech (TTS) voice is enabled for your language. In order to select it, go to Regional & Voices, through    and select Language.

Then, choose your language, and you should* see the list of available voices, where the first one is usually the TTS one. Tap Download and Done.

*TTS voices are incorporated in CoPilot on iOS; while they are a free feature within Android devices, which might need to be switched on.

To enable TTS voices in Android, go to the device's  Settings, and to Language and Input > Text-to-Speech Output, to select your preferred TTS engine, and install it.

To enable the TTS voices on iPhone, go to the device's Settings > Accessibility > VoiceOver > Speech > Voice to download your preferred voice.

Once you've done this, launch CoPilot and follow the instructions above, to enable the TTS voice.
