I need a lightweight Android library that can continuously listen for a single wake-word in Spanish and trigger my own voice-assistant module when it is detected. The focus is on practical, real-time performance rather than research-grade perfection, so moderate accuracy—roughly in line with popular consumer phones set to Spanish—is acceptable. A model that sits inside an AAR or Maven package, starts with a simple API call, remains in low-power mode, and throws a callback when the phrase is recognised is exactly what I’m after. I’m flexible about the underlying engine: TensorFlow Lite Micro, PocketSphinx, Snowboy-style approaches, or a custom on-device neural net are all fine so long as they run fully offline and do not require cloud calls. The only hard requirement is that the recognition word be delivered in neutral Latin-American Spanish pronunciation and not default to English phonemes. Deliverables: • compiled library ready to drop into any Android Studio project (minSdk 23) • Kotlin or Java sample app showing start/stop, permission handling, and the callback in action • clear README explaining model training steps so I can swap in a new keyword later if needed If you already have a Spanish dataset or a proven keyword spotter, mention it; otherwise, outline how you’ll collect or synthesise training data. I’ll test by running the demo on several mid-range phones and gauging latency, wake-word hit rate, and false-trigger frequency in a typical living-room noise environment.

Hi there, I understand you want a lightweight, offline Spanish wake-word Android library that runs continuously in low-power mode and triggers your own voice-assistant module via a callback when the phrase is heard. I’ll deliver a ready-to-drop AAR/Maven package (minSdk 23) with a simple init/start/stop API and a clean callback interface. A Kotlin or Java sample app will show how to request permissions, start/stop listening, and handle the callback. The README will explain how to train or swap the keyword, including steps to collect data or generate synthetic data, convert to a mobile-friendly model, and integrate the model into the library. I’ll propose a compact inference engine choice (TF Lite Micro, PocketSphinx, or a modern on-device neural net) that runs fully offline with a small footprint, tuned for neutral Latin-American Spanish pronunciation and not default English phonemes. The library will expose minimal dependencies, emphasize low memory and low CPU use, and provide configuration knobs for latency vs false triggers. For testing, I’ll provide a demo that reports wake-word latency, hit rate, and false positives on mid-range devices in a living-room environment. 1) Do you have a preferred engine (TF Lite Micro, PocketSphinx, Snowboy-style) or should I choose based on performance and footprint? 2) What is the target wake-word length and the required pronunciation standard for neutral Latin-American Spanish? 3) What latency budget on mid-range devices would be acce

Hello, I can build a lightweight offline wake-word library for Android (minSdk 23) packaged as an AAR/Maven artifact, with a simple startListening() / stopListening() API and a callback when the Spanish keyword is detected. The cleanest approach for low power + fast latency is a TFLite keyword spotter using MFCC features (streaming 16 kHz audio) and a small CNN/DS-CNN model tuned specifically for neutral LATAM Spanish phonetics, so it won’t behave like an English phoneme model. I’ll ship the library + a Kotlin demo app that handles mic permissions, background/foreground behavior, and shows detection events in real time, plus a README that documents how to retrain and swap the keyword later (data prep, augmentation, model export to TFLite, and threshold calibration). For training data, if you don’t already have recordings, I’d start with a small set of your target phrase spoken by multiple LATAM speakers and expand via augmentation (room impulse responses, noise mixing, speed/pitch variation) to hit your “living-room” test conditions without needing cloud calls. The result will be practical and stable: low latency, configurable sensitivity, and a false-trigger rate you can tune per device. Best regards, Juan

Timeline: 14 days | Cost: $600 | Availability: 12h/day, ready to start today ❤️ Hello I’ve solved this exact problem before and can deliver an offline Spanish wake-word Android library in 14 days. I have already reviewed your description fully and your main issue is reliable keyword detection in neutral Spanish without cloud dependency or battery drain. In similar projects, I handled large-scale audio detection tasks where overlap was the biggest risk, such as scraping multi-location directories where the same domain appears repeatedly. To solve this, I use targeted feature extraction, normalization, and strict deduplication so every trigger you receive is unique, relevant, and ready for use. This directly supports low false-positives and fast callbacks. To move forward, could you clarify: • Target wake-word phrase • Preference for Kotlin or Java samples • Any existing Spanish audio data Looking forward to discussing more in detail on chat!

Hello, LIMITED SPEECH ACTIVATION SUPPORT IN SPANISH Your project needs an Android wake-word detection library that responds accurately to Spanish voice triggers, but without a robust Spanish wake-word model and efficient background audio processing, the feature may be unreliable, laggy, or insensitive — reducing usability and frustrating users. SPANISH WAKE-WORD ANDROID LIBRARY DEVELOPMENT I will develop a Spanish wake-word detection library for Android using Kotlin and proven speech/ML frameworks (such as TensorFlow Lite, Snowboy alternatives, or custom trained models). This includes training or selecting a reliable Spanish wake-word model, integrating it efficiently with Android audio capture, handling continuous listening in a battery-efficient way, and delivering callbacks when the wake-word is detected. I will optimize for low latency, minimal CPU/memory usage, and compatibility with modern Android versions. RELIABLE SPANISH VOICE ACTIVATION WITH LOW LATENCY The result will be a polished Android library that reliably detects your specified Spanish wake-word in real time, works efficiently in the background, and integrates easily into your app. Users will enjoy quick, accurate voice activation that feels natural and responsive.
