It runs Gemma 4 E2B (2.3B effective parameters) via the LiteRT-LM runtime entirely on-device, with no cloud dependency after setup. Hardware includes a Pi 5 with 8GB RAM, a display, microphone, speaker, and a custom keypad PCB. Text-to-speech uses the open-source Moonshine engine, and a unified script launches the LLM server, Python API, and React frontend. A demo video shows Spanish-Mandarin interpretation with low latency. Source code, enclosure STL files, and setup instructions are available on GitHub, alongside related Raspberry Pi blog posts on optimizing LiteRT performance. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What model and runtime does the Gemma Translator project use to run offline voice translation on a Raspberry Pi 5? It uses Google's Gemma 4 E2B model, which has 2.3B effective parameters (about 5.1B total with per-layer embeddings), run through the LiteRT-LM orchestration layer built on top of LiteRT. This lets the Raspberry Pi 5 perform on-device speech translation entirely offline after initial setup, with no cloud connection required. _Developers building offline edge AI translation tools can track LiteRT and Gemma updates on daily.dev._ ### What text-to-speech engine works well for low-latency AI voice agents on embedded hardware like Raspberry Pi? The Moonshine open-source engine handles text-to-speech in the Gemma Translator project, chosen specifically for its low latency in AI agent applications. It converts translated text back into spoken audio output on the Raspberry Pi 5, keeping the interpreter's response time usable for live conversation. _Anyone picking a TTS engine for edge AI voice apps can follow related tooling news on daily.dev._ ## Similar posts on daily.dev - [TranslateGemma : Open translation on Google models, supporting 55 languages](https://daily.dev/posts/translategemma-open-translation-on-google-models-supporting-55-languages-tywukq9px) · Product Hunt · 0 upvotes · 0 comments --- Tags: [#raspberry-pi](https://daily.dev/tags/raspberry-pi), [#local-ai](https://daily.dev/tags/local-ai), [#gemma](https://daily.dev/tags/gemma) [View this post on daily.dev](https://daily.dev/posts/gemma-translator-multilingual-interpreter-runs-locally-on-raspberry-pi-5-with-the-litert-runtime-2tivbidnk) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Gemma Translator multilingual interpreter runs locally on Raspberry Pi 5 with the LiteRT runtime","url":"https://daily.dev/posts/gemma-translator-multilingual-interpreter-runs-locally-on-raspberry-pi-5-with-the-litert-runtime-2tivbidnk","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/gemma-translator-multilingual-interpreter-runs-locally-on-raspberry-pi-5-with-the-litert-runtime-2tivbidnk"},"datePublished":"2026-08-14T07:04:15.661Z","dateModified":"2026-08-15T04:00:23.311Z","description":"An open-source project called Gemma Translator turns a Raspberry Pi 5 into a fully offline, real-time multilingual voice interpreter, built by three Google...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1913751fbdb22ac58171357430110343?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1913751fbdb22ac58171357430110343?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"CNX Software","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Person","name":"CNXSoft","url":"https://daily.dev/cnxsoft","image":"https://avatars.githubusercontent.com/u/1366138?v=4","interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"EndorseAction"},"userInteractionCount":490}},"commentCount":0,"discussionUrl":"https://daily.dev/posts/gemma-translator-multilingual-interpreter-runs-locally-on-raspberry-pi-5-with-the-litert-runtime-2tivbidnk","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"raspberry-pi,local-ai,gemma","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"CNX Software","item":"https://daily.dev/sources/cnx-software"},{"@type":"ListItem","position":3,"name":"Gemma Translator multilingual interpreter runs locally on Raspberry Pi 5 with the LiteRT runtime"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/gemma-translator-multilingual-interpreter-runs-locally-on-raspberry-pi-5-with-the-litert-runtime-2tivbidnk#faq","mainEntity":[{"@type":"Question","name":"What model and runtime does the Gemma Translator project use to run offline voice translation on a Raspberry Pi 5?","acceptedAnswer":{"@type":"Answer","text":"It uses Google's Gemma 4 E2B model, which has 2.3B effective parameters (about 5.1B total with per-layer embeddings), run through the LiteRT-LM orchestration layer built on top of LiteRT.
