Hmm well, Open Alexa app then go to setting section. Click on Alexa Account then will show some options like Recognised Voices, Kid skills, Voice Purchasing, Alexa Voice responses, and History. Fine! now you click on Recognised Voices then Create a User Voice Profile. it will help Alexa to call you by name & improve your personalized section with your Voice. By tapping “BEGIN“ you can create a voice profile. Make sure Supported Devices are connected properly to capture your voice. If already created with other’s voice then delete it and recreate it with your own Voice Profile. Thanks
