Doorbell 2 voice volume is at max

Ring doorbell 2two way talk volume far to loud, just bought this only to discover the volume at the bell unit is far to loud so much so people in other streets can hear me talk to the postman. Is there away to turn down the volume?I know there is a slider for the chime volume but nothing to control the actual 2 way coms I find that extremely poor design if that's the case? Anyone have same problem or advice Thanks
