Gladia Web Voice Order Module

I need a JavaScript module that lets customers dictate complex hardware orders directly inside my web store. Using the Gladia speech-to-text API, the module must:

• stream microphone input, display a simple push-to-talk UI, and show live transcription
• recognise technical terms such as lengths, diameters, part numbers, and quantities, then convert each spoken line into clean JSON that my cart can consume (e.g., { "sku": "AB-45-ST", "qty": 12, "length": "1.25m" })
• expose hooks so I can pass the JSON straight to existing checkout code
• allow easy extension of the custom vocabulary so future parts or units can be added without code rewrites

Deliverables
1. Well-commented source code for the Gladia integration, parser, and lightweight UI component (vanilla JS or ES6; no build chain assumptions).
2. A user manual that explains set-up, vocabulary tweaks, and how to embed the module on any web page.
3. Quick-start demo page so I can test ordering scenarios immediately.

Acceptance is complete when I can speak at normal speed, see the JSON appear in the console within two seconds after finishing a sentence, and import the module into another page with a single script tag.
