Talker problem

[Prajdo]

Hi everyone. I have a little problem with some coding again.

This time I'm trying to add custom prefab with function to talk something randomly. After some time I came up with something like this:

local talk_time = 10 * (0.8 + 0.4 * math.random()) 
        inst:DoPeriodicTask(talk_time, function(inst)
            local x, y, z = inst.Transform:GetWorldPosition()
            local ents = GLOBAL.TheSim:FindEntities(x, y, z, 16, { "player" })
            ent = ents[1]
            
            if ent and ent.userid ~= nil then
                if math.random() < 0.5 then
                    inst.components.talker:Say("X")
                    inst.SoundEmitter:PlaySound("Z", "talk") 
                else
                    inst.components.talker:Say("Y")
                    inst.SoundEmitter:PlaySound("Z", "talk") 
                end
           end

        end)

My prefab is talking properly. It can say both "X" and "Y" randomly but my problem is with soundemitter which is triggering only once. I don't know how should I write it the way so each time my prefab is talking a sound is repeated. Maybe someone have any ideas?
