Hello, As a result of a detailed review of your project requirements, I fully understand the goal of building a wearable vocal training device with real-time feedback and a connected mobile experience. I have experience handling similar sensor-based and mobile-integrated projects and I’m available to start your project right now. I bring deep expertise in Embedded Systems, Bluetooth (BLE), Mobile App Development (iOS/Android), Audio Processing, and Prototyping with over 10 years of experience. One of the key challenges in projects like this is achieving low-latency, accurate feedback from sensors to the mobile app, so I would design a wearable prototype with optimized sensor data capture, BLE communication, and a mobile interface that visualizes vocal metrics in real time with smooth, responsive feedback. I have worked on similar real-time data systems combining hardware and mobile apps, focusing on stability, performance, and user-friendly interaction. I have a couple of quick questions. • Do you already have specific sensors in mind (e.g., vibration, microphone, EMG), or should I help define the hardware stack? • Should the first version focus on a working prototype or a production-ready device? I would be glad to discuss further details and can outline a clear timeline once requirements are finalized. Ready to get started immediately. Best regards, Carlos

Hi, I’m a US-based certified electronics and embedded firmware engineer with hands-on experience developing wearable sensor systems, low-latency DSP pipelines, and Bluetooth-connected devices, making me well-aligned with your vocal training product vision. I have previously designed neck-mounted and contact-based sensing systems using piezoelectric and vibration sensors similar to your concept, including analog front-end design, filtering, and real-time signal acquisition. My approach would follow a structured architecture: vibration sensing at the laryngeal region, low-noise signal conditioning, high-resolution ADC, and embedded DSP to extract vocal parameters such as pitch, vibrato, and harmonic content with sub-20 ms latency. I would implement efficient Bluetooth Low Energy communication to stream processed data to a custom mobile app, where I can also support development of an intuitive UI for real-time visual feedback and training insights. On the firmware side, I specialize in optimizing real-time processing pipelines and power-efficient wearable operation, ensuring stability and comfort for continuous use. Deliverables will include complete hardware design (schematics, PCB, BOM), embedded firmware, BLE protocol, mobile app (or API support), and a tested prototype ready for iteration or production. A functional prototype can typically be delivered within 6–8 weeks, followed by refinement and production support based on your feedback and testing results. Jared
