[Freeswitch-users] Capture DTMF and play and detect speech in Lua

[Manuel Durán Aguete]

Hello,

I'm trying to capture DTMF when doing play_and_detect_speech:

function capture_dtmf(session,input_type,data,arg)
        if input_type == "dtmf" then
                freeswitch.consoleLog("CRIT","Key pressed: " ..
data["digit"] .. "\n")
        end
end

session:answer()
session:sleep(1000)
session:setInputCallback("capture_dtmf","true")

session:execute("play_and_detect_speech",
"phrase:wellcome detect:unimrcp
{start-input-timers=false,no-input-timeout=5000,recognition-timeout=5000,
speech-language=es-ES}builtin:grammar/digits")


xml = session:getVariable('detect_speech_result')
if xml ~= nil then
        freeswitch.consoleLog("CRIT", xml .."\n")
else
        freeswitch.consoleLog("CRIT", "No result!\n")
end

The asr seems to work, but when no dtmf is captured in capture_dtmf. Is
DTMF capture with input callback supported by play_and_detect_speech ? Need
to use detect_speech ?

Thank you. Regards.
