Speech-to-text IVR

Is there a good option to create voice prompt IVR menu in FreePBX? This way instead of pressing any keys, the end user can just say the options to navigate the IVR.

This is possible, but you would need to do it custom (outside the FreePBX interface).

Is there a recommended option?

No, since it is all custom. For speech recognition Microsoft, Google and Amazon all work well for speech recognition, support multiple languages, and continue to improve without you needing to change anything. There are potentially local engines you could download and try, but I have no experience with those applications.

vosk is one solution, it is well-priced and can run in a docker container or on as little as a Rasperry and has asterisk integration
