A voice bot is a conversational agent that utilizes artificial intelligence and natural language understanding (NLU) to interpret the intent and meaning of its conversational partner's speech. Like a voice bot, a chatbot is an automated conversational interface powered by artificial AI, which you can use to automate and streamline your early-stage customer service interactions. Voice bots utilize input voice recognition and translation in conjunction with a text-to-speech (TTS) engine to comprehend human speech and respond in everyday language.
