So is it simply converting a text bot with voice elements, then you will get a voicebot ? Technically yes, but there are much more needed to be considered.


首先,你的Chatbot必先為擁有人工智能自然語意處理(natural Language Processing)、語音識別系統(Automatic Speech Recognition)和語音合成系統,Chatbot和Voicebot使用的方式和構造也不同,若不先重新設計產品,最後只會失敗收場。


Your Chatbot has to be A.I. based with Natural Language Processing unit, equipped with Automatic speech recognition ASR and Text to speech TTS engine. The environment of chatbot and voicebot is very different, if you just simply turn your text bot into voice without redesigning your product, is definitely a failure when it is used.


Voicebot沒有可見的元素,如按鈕、列表、建議答案和選項等文字Chatbot的元素,Voicebot僅利用聲音導航。在建立Voicebot時,人們應該要清楚了解Voicebot要幫你處理甚麼難題,它不能幫你處理所有的事務,而事實上它也不應該需要。


There are no visual elements like menu button, list, quick reply or carousels like the CUI provided by text chatbot. Instead, voicebot is simply a voice user interface (VUI), voicebot cannot answer everything you ask, and infact, it should not be. Producers have to carefully consider how users could understand what particular services voicebot can serve.


簡單就好

Keep it Simple


A.I. Voicebot可處理具清晰目標的任務,如處理預訂服務及回答常見問題。由Google研發的A.I. Duplex曾被報導以人工處理訂位服務,因人工智能難以處理人類複雜的對話內容,看起來要建立一個完美的Outbound Call,在設計其流程暫時仍需不少努力。但另一方面,處理Inbound預訂電話則簡單多了。

為甚麼Voicebot這麼重要?

Why is it important to consider of building a voicebot?


人口老化亦可能是原因之一。2030年,美國所有Baby Boomers時期出生的人口都會超過65歲,中國四分之一的人口亦會超65歲,勞動力開始下跌。為保持高質素的生活品質,重覆性的工作由機械人處理會較佳。爆發新冠肺炎後亦留意到,當有大量查詢時往往有些企業難以處理如此大量的電話查詢,如旅行社難以處理突發及大量的緊急查詢。


Aging problem could be one of the reasons. In 2030, all baby boomers will be older than 65 in the United States, and a quarter of people in China is over 65. There are not enough young people to work. To sustain the high living quality, repetitive work have to be passed to robots to handle. The outbreak of Covid-19 reveals that there are always not enough people to handle telephone calls in emergency situations.
