Yes, Dragon NaturallySpeaking speech recognition software supports Portuguese. You can choose to dictate in Portuguese and the software will recognize your speech and convert it to text in real time. However, it’s important to note that the level of accuracy may vary based on factors such as your accent, speech clarity, and the quality of your microphone. Additionally, you may need to purchase a version of Dragon NaturallySpeaking that specifically supports Portuguese, as some versions may only support certain languages.
