摘　　要：AI音频技术在当前电影对白和音效制作领域备受关注且已逐步应用到实际制作中。本文介绍了AI音频技术的主要概念及发展概况,对现阶段AI音频制作工具进行了分类整理,并按照电影对白和音效制作中声音生成与声音处理两大应用场景,探讨AI音频技术在电影对白和音效制作中的应用进展与未来前景。研究表明,目前AI音频技术可用于部分场景和部分类别的对白生成,但缺乏复杂情感表达能力;在动效和音响效果生成中可完成一定的素材准备,但精确度和丰富度有待提高。在声音处理方面,AI音频技术具备较强的音频降噪及增强、对白音色替换、动态及响度控制、音色及空间处理能力,在声音编辑和预混中已得到实际应用,但尚无法胜任声音设计、混录等需要高度依赖艺术创造力的环节,暂不具备独立完成整部电影声音制作的能力。AI audio technology is currently receiving a lot of attention in the field of present film dialogue and sound effects production and has gradually been applied to practical production.This paper introduces the main concepts and development status of AI audio technology,classifies while also sorts out current AI audio production tools,and discusses the progress and prospects of AI audio technology in the application of film dialogue and sound effects production,focusing on the two application scenarios of sound generation and sound processing.The research shows that at present,AI audio technology can be used for some scenarios and categories of dialogue generation,but lacks the ability to express complex emotions.Besides,it can also complete partial material preparation in Foley and sound effects generation,but its precision and richness need to be improved.In terms of sound processing,AI audio technology has strong ability on audio noise reduction and enhancement,dialogue voice change,dynamic and loudness control,tone processing,and space processing.It has been practically applied in sound editing and premixing,but it is not yet capable of meeting the high artistic creativity required for tasks such as sound design and re-recording mixing,so it has yet to have the ability to complete the sound production for a film independently.
