Two Voice Devs

Recorded on location at the Android Dev Summit, Allen Firstenberg is joined by Google Developer Expert and TabGeeks creator Jesse Nolan to dive into the rapidly evolving world of intelligent eyewear, XR headsets, and always-on AI assistants. Jesse shares his real-world journey as an early adopter across the wearables spectrum—from learning why sizing matters on the Meta Ray-Ban smart glasses to testing the Meta Display glasses with their neural interface wristband, Snap Spectacles, Samsung Galaxy XR, and the newly announced XREAL Aura.Together, Allen and Jesse examine the divide between immersive AR/VR headsets built for specialized experiences and lightweight, assistive smart glasses designed to be everyday daily drivers. They explore how Google's Android XR aims to unify four distinct device categories under a single operating system and partner ecosystem, and debate where emerging form factors like camera-less audio glasses, AI smart rings, and camera-equipped earbuds fit into the equation.Finally, they unpack the biggest developer revelation from the summit: how to actually build for Gemini across these devices. From the new alpha for Gemini Connected Apps to hooking up Python-based MCP servers with Google's privacy-first testing and deployment model, this episode captures the excitement—and the open questions—as developers get closer than ever to building a real-life Jarvis.Learn More:Jesse's Channel: https://www.youtube.com/@tabGeeksConnected Apps: https://developers.google.com/connected-appsAndroid XR: https://developer.android.com/develop/xrTimestamps:[00:00:00] Welcoming guest Jesse Nolan at the Android Dev Summit[00:01:24] Daily life with Meta Ray-Ban AI glasses: Sizing, always-on AI, and quick capture[00:03:48] Meta Display glasses, shopping lists, and the neural interface band[00:06:19] Snap Spectacles, XREAL Aura, and niche AR use cases vs. daily drivers[00:08:23] Android XR: One operating system across headsets and intelligent eyewear[00:10:40] Gemini as the unifying layer, the "Jarvis" dream, and Google's partner strategy[00:12:47] Camera-less AI glasses, smart rings, earbuds, and what defines Android XR[00:15:34] Developing for Gemini: Connected Apps, MCP servers, and privacy at the core[00:18:03] Outro and where to connect with Jesse Nolan#AndroidXR #SmartGlasses #IntelligentEyewear #GeminiAI #AndroidDevSummit #MetaRayBan #XREALAura #WearableTech #VoiceFirst #AIAgents #MCP #ConnectedApps #GoogleDevelopers #TwoVoiceDevsEpisode 280

Happy 6th Anniversary to Two Voice Devs! In this milestone episode, Mark Tucker and Allen Firstenberg look back at six years of podcasting and discuss how the industry is coming full circle. We started in the era of hardware assistants like Alexa and Google Assistant, shifted into text-based LLMs, and are now witnessing the return of voice-first interfaces through smart glasses and conversational LLM voice modes.As developers rush to build the next generation of AI agents, are we repeating the painful mistakes of the past? Mark and Allen share six critical lessons today's agent developers must learn, covering the abysmally poor developer-to-consumer discovery experience, the puzzle of monetization for independent creators, the true meaning of "voice first, not voice only," the absolute necessity of concise responses, the lost art of crafted entertainment over just-in-time generation, and why we need asynchronous interactions modeled after the Star Trek computer.If you're thinking about the next wave of agents in all sorts of form factors and modalities, this is the episode for you to watch. And we'd love to hear your take on what we've learned and what we still need to learn.[00:00:00] Celebrating six years of Two Voice Devs![00:01:00] The full circle return of voice-first LLM interfaces[00:03:59] Lesson 1: The discovery and installation bottleneck[00:08:59] Lesson 2: The monetization puzzle for indie developers[00:10:48] Platform plays: Android's advantage vs. Amazon's closed beta[00:16:50] Lesson 3: Designing for "voice first, not voice only"[00:18:45] Lesson 4: LLMs are too verbose—managing output conciseness[00:20:09] Lesson 5: Tailored entertainment and crafted storytelling[00:23:13] Lesson 6: Latency, response times, and the Star Trek computer[00:24:42] Outro and looking ahead to another year#VoiceFirst #AIAgents #GenerativeAI #SmartGlasses #IntelligentEyewear #VoiceUX #AmazonAlexa #GoogleAssistant #Gemini #AndroidXR #OpenAIEpisode 278

In this episode, Allen Firstenberg and Sam Witteveen dive into one of the newest and most discussed concepts in the developer community: the "Agent Harness." What exactly is a harness, and how does it transform a simple, one-shot AI model into a truly capable, autonomous agent?Sam and Allen demystify this new paradigm, tracing its evolution from early frameworks like LangChain and LangGraph to the modern, bespoke, "off-the-rails" architectures powering tools like Claude Code, Hermes Agent, and Antigravity. They explore essential best practices—including sandboxing, persistent file access, agent loops, planning tools, and fine-grained security—and weigh the critical trade-offs between highly customizable single-tenant deployments and scalable, cloud-managed multi-tenant agent infrastructures. Whether you are prototyping with managed APIs or writing custom scaffolding in Python, Go, or Rust, this episode provides a clear map of the shifting landscape of agent engineering.[00:00:00] Catching Up & the Summer of AI Evolution[00:01:07] What is an Agent Harness?

Roll tape and prompt! In this episode of Two Voice Devs, Allen and Mark explore how Google’s new advanced prompting guidelines turn developers into voice directors for Gemini Text-to-Speech. Instead of coding rigid SSML tags, you can now establish a scene, write stage directions, and give "director's notes" to shape a base voice's gender, accent, style, and pacing.Allen showcases a web app where he directs a single base voice—to play two entirely different characters: a rough Brooklyn cab driver and a classic Southern belle. The hosts discuss using natural language audio tags as cues for laughter, sighs, gasps, and more, and how these theatrical controls are coming alive in real-time with Gemini Live and Gemini 3.1 Flash TTS.Learn more:* https://ai.google.dev/gemini-api/docs/speech-generation[00:00:05] Welcome to Two Voice Devs[00:00:27] Intro to Gemini Text-to-Speech and Advanced Prompting[00:01:57] Moving Beyond SSML to Flexible Base Voices[00:03:07] Prompting Genders and Accents (The Storytelling Analogy)[00:04:40] Web App Demo: Zephyr as a Brooklyn Cab Driver vs. Southern Belle[00:06:50] Building Multi-Voice Conversations with Stage Directions[00:08:41] Using Natural Language Audio Tags for Expressive Cues[00:11:02] Gemini Live Integration and Dynamic Tone Selection[00:12:27] Model Details: Gemini 3.1 Flash TTS Preview and Release Info[00:13:53] Wrap-up and Call for FeedbackHashtags:#GeminiTTS #TextToSpeech #GenerativeAI #GoogleDeepMind #GeminiLive #GeminiFlash #AIStudio #DeveloperTools #SpeechSynthesis #VoiceFirst #AdvancedPromptingEpisode 275

After months of conferences and busy schedules, Mark Tucker and Allen Firstenberg return to discuss Microsoft’s surprising Build conference announcement: Project Solara. Moving from the legacy voice-first consumer world of Amazon Alexa and Google Assistant, Microsoft is pioneering a secure, business-focused "Agent-first" platform.In this episode, we unpack Microsoft's two new concept devices, a desktop smart display and a wearable camera-equipped badge, and explore the Android Open Source Project (AOSP)-based platform behind them: the Microsoft Device Ecosystem Platform (MDEP). We discuss how Project Solara integrates enterprise security standards like Intune, Windows Hello for Business, and Entra ID to allow agents to act on behalf of authenticated users. We also dive into the future-proof promise of "Just In Time UI" (Generative UI) which dynamically adapts interfaces to any form factor, and explore how these agentic tools could liberate deskless workers from being "slaves to a slab of glass."More Info:* https://commandline.microsoft.com/project-solara-build-2026/Timestamps:[00:00:00] Intro & Catching Up[00:00:49] Transitioning from Voice-First (Alexa/Assistant) to Agent-First[00:01:35] Designing for Echo Show and Google Assistant vs. GenAI[00:02:37] Project Solara: Custom Agentic Devices for Business[00:03:09] Google Glass & the Early Spark for Enterprise Use Cases[00:04:30] Smart Displays and Wearable Badge Concept Hardware[00:05:12] Built on Android (AOSP) vs. Google's Android XR[00:05:46] Security: Microsoft MDEP, Intune, and Alexa for Business[00:07:10] Bring Your Own Agent (BYOA) on Azure[00:08:41] Just-In-Time UI & Generative UI[00:12:09] Developer Availability and Future Outlook[00:13:26] Rethinking Computers: Lessons from Google Glass & Assistant[00:14:32] Wrap Up and Future Form Factors (Watches, Rings, Glasses)#ProjectSolara #MicrosoftBuild #AgentFirst #VoiceFirst #MDEP #GenerativeUI #GenUI #AOSP #BYOA #EnterpriseTech #TwoVoiceDevsEpisode 274
