I’m building a fully-featured voice assistant that users can download on both iOS and Android. Think of it as a pocket-sized helper that can listen, understand, and act on spoken commands—setting reminders, fetching quick answers, controlling smart-home services via API, or triggering in-app actions. Here’s what I need from you: • A native or cross-platform mobile app (Swift/SwiftUI + Kotlin, or Flutter / React Native—whichever lets us land on both stores quickly and cleanly). • On-device and cloud speech recognition so the assistant responds within a second or two, even on slow connections. • Natural-language understanding: basic intent detection, entity extraction, and a fallback to a large-language-model endpoint when the user asks something outside our hard-coded skills. • A simple, voice-first UI: press-and-hold microphone button, animated waveform, and a conversational transcript that scrolls. • Hooks to add new “skills” by hitting REST endpoints—no hard recompiles each time we extend capabilities. • Deployment-ready builds and a README showing how to run, test, and ship to TestFlight and Google Play Internal Testing. Acceptance criteria (to keep us both clear): 1. User launches the app, taps the mic, speaks a command, and gets a spoken + on-screen reply in under 3 seconds on a typical 4G connection. 2. Both iOS (14+) and Android (8.0+) install packages pass store linting with no critical warnings. 3. Source code is cleanly organised, documented, and pushed to the private repo I’ll share. 4. A one-page PDF or markdown doc summarises architecture choices and how to add new intents. I’d like to see a working MVP inside three weeks and use the final week for polish and submission. If this sounds like your wheelhouse, let’s get talking right away.

Hi There, 1.I’m building a fully-featured voice assistant that users can download o... ==> We completely understand your vision for a pocket-sized voice helper. We have developed similar AI-driven applications in the past. One project included a very smart feature where the assistant would learn user habits and proactively offer suggestions based on their location or time of day, which made it feel truly personal. We got the idea about the technical requirements youve laid out. For quick and clean development on both iOS and Android, we would suggest using Flutter. It is excellent for creating beautiful, natively compiled applications from a single codebase. We will implement a responsive system combining on-device and cloud speech recognition for fast replies and build a simple, voice-first interface as you described. The plan to add new skills via REST endpoints is a solid, scalable approach we will follow. ## Queries : 1. When a users command requires the fallback to a large-language-model, should the app display a specific indicator to manage user expectations for a slightly longer response time? ## Initial Project Structure : - Splash - Main Assistant - Settings - Onboarding - Available Commands We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

Hi, This is Elias from Miami. You’re not just building a voice UI here — the real challenge is delivering a fast, reliable assistant architecture that feels responsive on mobile while staying flexible enough to grow through new skills, APIs, and LLM-backed fallback flows. The 3-week MVP target is realistic if we keep V1 focused on core voice loops, intent routing, and clean extensibility. I would structure this as a cross-platform app in Flutter or React Native for speed to both stores, backed by a modular intent/router layer, speech pipeline, and skill execution service. Core flows would cover STT, intent/entity handling, REST-based skill hooks, transcript UI, TTS reply, and LLM fallback, with careful attention to latency, offline tolerance, and store-ready packaging. I build scalable mobile systems where UX speed, maintainable architecture, and API extensibility matter from day one. This project needs clean separation between voice capture, NLU, skills, and fallback intelligence so new capabilities can be added without rebuilding the app each time. Q1: Do you already have preferred providers for STT, TTS, and LLM fallback, or should I propose the fastest MVP stack? Q2: For smart-home actions, are there specific APIs/devices that must be supported in V1? Q3: Should the first release support authenticated user accounts, reminders, and persistent conversation history, or keep V1 stateless?

Hi there, We’ve developed several voice-enabled apps, including a smart home assistant that integrates with Alexa and Google Home. We used Azure and Google Cloud for speech-to-text and text-to-speech, and we built a custom LLM to handle user queries and control devices. This experience gives us a strong foundation in creating reliable, production-ready voice solutions. For your project, I recommend using a hybrid approach with both on-device and cloud-based speech recognition. This way, we can ensure fast responses even on slow connections. We can also implement a fallback mechanism to switch to a large language model when needed. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit. I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best, Adil

Hello, I understand you are building a cross platform voice assistant that can listen to spoken commands, interpret user intent, and trigger actions through APIs or built in capabilities. The goal is to deliver a fast voice first experience with near real time responses, extensible skill integrations, and clean deployment to both iOS and Android. I can develop this as a cross platform mobile application using Flutter or React Native to accelerate development while maintaining smooth performance on both platforms. The architecture will combine on device speech capture with cloud speech recognition, a lightweight intent detection layer, and a fallback to an LLM endpoint for open ended queries. The interface will include a voice first UI with a press to talk interaction, animated waveform feedback, and a scrolling conversation transcript. The system will also support modular skill endpoints so new features can be added through APIs without rebuilding the app. Before delivery, I will test response latency, device compatibility, and store compliance to ensure smooth TestFlight and Google Play internal testing deployment.

Hello, I have reviewed the details of your project. i will create the mobile assistant using react native so the same codebase runs on ios and android. the voice capture flow will start with a microphone press action that records audio and sends it to speech recognition using google speech to text api with a fallback local speech engine for quick response when network is slow. the recognized text will move to a node.js service that handles intent detection and entity parsing using a simple intent classification layer and openai api for complex questions. the app will return results through text and voice using text to speech while showing a scrolling transcript and waveform animation in the react native interface. each assistant skill will call external services through rest api endpoints so new actions can be added without changing the mobile code. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you. Thanks Best Regards, Mughira

This is exactly the kind of real time, voice first system I enjoy building. The scope is clear and the three week MVP target is realistic with disciplined architecture. I would use React Native to ship simultaneously to iOS and Android while keeping a single shared codebase. Performance critical audio capture and playback would leverage native modules where necessary to ensure sub three second round trip latency. For speech recognition, I would combine on device STT for fast initial capture with cloud streaming for higher accuracy and fallback. Intent detection and entity extraction would run through a lightweight NLU layer first, with structured routing to predefined skills. For open ended queries, the system would fall back to an LLM endpoint with guardrails. The UI would remain minimal and voice first: press and hold mic, animated waveform, live transcript, and spoken response. Skills would be modular and defined as REST integrations so new capabilities can be added without rebuilding the app. Code would be cleanly layered into audio, NLU, skill router, and UI modules. I would provide TestFlight and Google Play internal builds, full documentation, and an architecture summary. MVP timeline 3 weeks plus 1 week polish and submission.
