About Cosyvoice V3 Flash

为持续更新的文稿配音

CosyVoice-v3-Flash 能将文字实时流式合成为语音,适合课程说明、产品讲解、客服回复和角色旁白。它关注自然度、音质、韵律与情感表现;需要自定义声音时,可以先用 5—20 秒参考录音创建复刻音色,再为后续文稿重复使用相应 voice ID。

模型的声音复刻支持多种语言,包括德语、西班牙语、法语、意大利语和俄语等。制作多语言版本时,分别准备各语言的准确正文,重点试听人名、品牌词和数字。复刻主要建立声音特点,不能代替文稿翻译、术语校对或实际试听。

根据音色选择指令方式

v3-Flash 的复刻与设计音色可以使用自由风格指令,描述语气、语速和表演方向。系统音色则要使用其支持的固定指令格式,不能把自定义音色的任意指令直接套用。做角色配音时,可先固定音色,分别试听平静解释与紧张提醒,确认情绪变化是否符合场景。

业务播报还需要处理文本的可读性:将缩写、长数字串和分隔符改写成易于听懂的表达。连续数字用点号“·”分隔时,本模型可能出现漏读或重复,可改用中文逗号并试听。长文按语义分段,避免在地址、金额或完整词语中间切开。

北京地域基准价为 1 元/万计费字符,输出音频不另收费。汉字通常计 2 个字符,SSML 标签不计入,按返回字符数结算。美元基准按 1 美元 = 6.8 元换算,最终费用应用账户分组倍率。

Use cases and prompting

角色讲解试音

使用已创建的本模型复刻或设计音色,输入正文:“别着急,我们先把地图展开。沿着河流一直向北,就能找到下一处标记。”

instruction:“像耐心带路的伙伴,语气自然,前句安抚,后句清晰强调方向。”

系统音色也能照写这段指令吗?

系统音色使用其支持的固定指令格式;上面的自由描述适用于复刻或设计音色。

数字播报漏读如何排查?

先检查正文分隔符。用“·”串联的数字可换成中文逗号,必要时改写为完整口语,再单独试听。
