Answer

AnveVoice lets visitors speak Sylheti to your site instead of typing. Recognition returns in roughly 168ms. One line of embed code, live in about two minutes.

Detailed Explanation

Sylheti recognition splits by geography in a way few languages do. In Bangladesh, speakers mix Sylheti with standard Bengali; in the UK diaspora, they mix it with English, and second- and third-generation speakers carry British English phonology into their Sylheti. Those are two genuinely different recognition problems wearing the same language name, and which one you need depends entirely on whether your customers are in Sylhet or in Tower Hamlets. Voice input matters especially for the older diaspora generation, many of whom speak Sylheti fluently but were never schooled in written Bengali and cannot comfortably type it — for them a Bengali-script text box is not a minor inconvenience but a closed door. Deployments that fit are UK-facing community, legal, health and financial services; remittance providers; and hospitality. We do not publish a Sylheti word-error rate, and we would be especially sceptical of one here given the two-population split. Send audio from the population you actually serve and we will measure it with you.

Key Takeaways

  • Visitors speak Sylheti instead of typing — recognition returns in roughly 168ms
  • Two different problems under one name: Sylheti–Bengali mixing in Bangladesh, Sylheti–English in the UK diaspora
  • Many older diaspora speakers are fluent but never schooled in written Bengali — a text box is a closed door

  • Free plan ($0, 50,000 tokens, 1 bot) to test against your own audio
