Is a woman's soft, gentle voice—especially when speaking foreign languages or Arabic—considered "khudu' bil-qawl" (softening of speech) and an act of undue compliance, and how can one distinguish between it and a normal voice to avoid "khudu' bil-qawl" when recording cooking videos?

The interpretations of the exegetes revolve around the idea that the forbidden softness in speech means that a woman should not soften or sweeten her voice in a way that would tempt someone whose heart harbors wickedness and desires fornication. Rather, she should make her speech rough and harsh when addressing non-mahram men.
