Voice Experiments with Raspberry Pi Pico + Hiwonder TTS Module

Raspberry Pi Pico Meets Voice Pronunciation 🎙️📢

Today’s quick exploration led me to test a fun voice interaction setup using the Raspberry Pi Pico and a Hiwonder Text-to-Speech (TTS) module. And guess what? It worked surprisingly well—well enough to spark ideas for more robust real-time voice interactions!

🛠️ Quick Overview of Today’s Experiment:

Using just:

• 🖥️ Raspberry Pi Pico (powered by MicroPython)
• 🎤 Hiwonder TTS module

I managed to convert text inputs directly into audible speech with minimal setup. The responsiveness and clarity were impressive—ideal for quick prototyping and small IoT projects.

🤔 Interesting Quirk: An Accent Emerges!

Though the output clarity was fantastic, the module adds a rather charming surprise—a noticeable Chinese accent when pronouncing English words. It made me smile but also highlighted an area for improvement.

🚀 What’s Next?

This experiment brings me one step closer to implementing seamless real-time voice interaction, which could be a huge leap forward for my ongoing IoT projects.

However, I’m now curious about exploring other TTS modules that might offer more natural-sounding English speech, especially those compatible with microcontrollers.

Got recommendations? I’d love to hear about your favorite TTS modules or solutions that provide clear, accent-neutral English pronunciation for embedded systems!

📢 Stay tuned as I continue experimenting—more voice adventures await!
