Do voice & video messages on websites actually boost engagement compared to plain text forms?

I've been seeing more and more tools popping up that let website visitors send voice notes or short videos instead of filling out cold text forms.

I'm genuinely curious about real-world results :

• Has anyone here tested voice/video widgets on their landing pages, apps, or sites?

• Did it meaningfully increase leads, form completions, reply rates, or conversions? Or did it backfire (e.g., people feel awkward recording themselves, bad audio/video quality, privacy concerns)?

• What use cases seem to work best? (B2B SaaS, e-commerce support, coaching/consulting, recruiting, customer interviews…?)

• UX-wise: do you make it optional or required? Does forcing voice/video feel pushy or creepy to some visitors?

• Any tech/privacy headaches? (GDPR consent, media storage, moderation of incoming videos, etc.)

Would love to hear honest experiences or even just your gut feeling if you haven't tried it yet.
