Voice-Enabled Shopping App Development

I’m building a mobile shopping app that lets customers add items to their cart either by typing or by speaking. After an order is placed, the system must automatically locate the nearest approved partner store, forward the request, and let that store confirm, pack, and dispatch the goods to the customer’s saved address or to their live GPS location.

Key requirements
• Dual input: standard text search plus real-time voice recognition.
• Product scope: Other categories beyond Groceries, Electronics, or Clothing; I’ll share the exact catalog, so the data model should remain flexible.
• Location logic: match an incoming order to the closest partner store based on distance and stock availability, then display expected prep and delivery times.
• Delivery workflow: once a store marks the order ready, trigger integrated courier dispatch and allow customers to track the driver on a map.
• Language support: single-language voice commands today, but structure the code so additional languages can be added later without a full rewrite.
• Admin tools: simple dashboard to onboard partner stores, approve products, set service areas, and review analytics.

I’m open to your choice of frameworks—React Native, Flutter, or a comparable cross-platform stack—as long as the final build is performant on both iOS and Android. For voice capture you may leverage established APIs like Google Speech or Web Speech, provided the solution keeps the door open for future multilingual expansion.

Please outline:
1. Your recommended tech stack.
2. A phased timeline (MVP through launch).
3. Examples of previous voice or geolocation-heavy apps you’ve delivered.

The first milestone will focus on an MVP with text and voice ordering, store matching, and basic delivery hand-off.
