This paper presents the proof-of-concept of the first automatic voice assistant ever built in Wolof language, the main vehicular language spoken in Senegal. This voicebot is the result of a collaborative research project between Orange Innovation in France, Orange Senegal (aka Sonatel) and ADNCorp, a small IT company based in Dakar, Senegal. The purpose of the voicebot is to provide information to Orange customers about the Sargal loyalty program of Orange Senegal by using the most natural mean to communicate: speech. The voicebot receives in input the customer's oral request that is then processed by a SLU system to reply to the customer's request using audio recordings. The first results of this proof-of-concept are encouraging as we achieved 22\% of WER for the ASR task and 78\% of F1-score on the NLU task.

本文介绍了首个用Wolof语建立的自动语音助手的概念验证。该语音机器人是法国Orange创新部、Senegal Orange（又名Sonatel）和位于Senegal达喀尔的小型IT公司ADNCorp之间的合作研究项目的结果。该语音机器人的目的是通过语音交流提供关于Orange Senegal的Sargal忠诚度计划的信息给Orange的客户。该语音机器人通过接收客户的口头请求，并使用语音录音来回复客户的请求是采用最自然的沟通方式。这个概念验证的初步结果令人鼓舞，ASR任务的错误率为22％，NLU任务的F1得分为78％。
