is it possible to capture user response from gather_input widget for an outgoing call java REST API call to twilio studio

Question

Usecase : System makes outgoing call via twilio sstudo and gathet user response Steps:

1. Outgoing call via twilio sdk v2 API to twilio studio.

2. Twilio flow Trigger REST API is configured to receive as incoming call

3. Make out going call widget[name = "call_user_1"] makes outgoing call

4. Gather Input on call widget [name ="gather_input"] capture ressponse

5. If I debug below java code , I see : ExcecutionStep name = "incomingRequest" ,transitionedFrom="Trigger",transitionedTo="call_user_1

6. So the code exists and it does not even gathet input.

7. Please see attached twilio flow and code

                break;
            }
        }

        System.out.println("executionStep=" + executionStep);

Answer 1

So I think I was making a mistake as there was no way to get response back after Say widget. So instead of ending in Say/Play widget after gathering input as user input keypad /speech from split widgets I added : http widget [name="http_1"] having 2 HTTP K-V with values being caputured from split keypress and speech widgets.

Widget name ="split_speech_result"

Variable to test="widgets.gather_input.Digits"

Widget name="split_key_press"

Variable to test="widgets.gather_input.SpeechResult"

Widget name= "http_1"

Http Parameters : key-"Digits" value-"{{widgets.gather_input.Digits}}" key-"SpeechResult" value -"{{widgets.gather_input.SpeechResult}}

Request URL : full uri of TwilioStudioReceiver rest controller for gatherResult

Below is Rest Controller with POST to receive callbacks

@RestController
@RequestMapping("/ivr")
@SuppressWarnings("ClassFanOutComplexity")
public class TwilioStudioReceiver {

    @PostMapping(value = "/gatherResult", produces = "application/xml")
    @ResponseBody
    public String handleGatherResult(
        @RequestParam(value = "Digits", required = false) String digits,
        @RequestParam(value = "SpeechResult", required = false) String speechResult) {

         
        System.out.println("speechResult=" + speechResult);
        System.out.println("Digits=" + digits);

        return null;
    }
}

Issue: I do not get speechResult everytime gathered but I can get digits everytime. Can anyone help?Does this mean speech gathering by twilio v2 sdk is not production quality
