24 alternatives to I trained a 9M speech model to fix my Mandarin tones
Built this because tones are killing my spoken Mandarin and I can't reliably hear my own mistakes. It's a 9M Conformer-CTC model trained on ~300h (AISHELL + Primewords), quantized to INT8 (11 MB), runs 100% in-browser via ONNX Runtime Web. Grades per-syllable pronunciation + tones with Viterbi forced alignment. Try it here: https://simedw.com/projects/ear/
This tool helps Mandarin learners improve their tone pronunciation by analyzing recorded speech directly in the browser. It uses a 9-million-parameter speech model trained on hundreds of hours of Mandarin audio to… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I built a voice agent from scratch that averages ~400ms end-to-end latency (phone stop → first syllable). That’s with full STT → LLM → TTS in the loop, clean barge-ins, and no precomputed responses. What moved the needle: Voice is a turn-taking problem, not a transcription problem. VAD alone fails; you need semantic end-of-turn detection. The system reduces to one loop: speaking vs listening. The two transitions - cancel instantly on barge-in, respond instantly on end-of-turn - define the experience. STT → LLM → TTS must stream. Sequential pipelines are dead on arrival for natural…

Luke from ElevenLabs here. We just released Scribe Realtime v2, our new real-time Speech to Text model. We rebuilt it from the ground up around a new architecture that uses predictive transcription – it anticipates the next likely word before it’s spoken. That makes it both fast (around 150 ms latency) and highly accurate. Scribe v2 Realtime outperforms every low latency transcription model across 30 commonly used EU and Asian languages – 93.5% accuracy, compared to Gemini 2.5 Flash (91.4%), GPT-4o MiniTranscribe (90.7%), and Deepgram Nova 3 (85%). It supports 90+ languages including…

Hey HN! We built Speech Meter as a tool to practice and improve English pronunciation. It uses AI to analyze your accent and score your pronunciation accuracy. It’s great for anyone who wants to practice their pronunciation in English. I’d love to hear your thoughts and suggestions for improvements. I really appreciate any feedback you could have (:

Hello Hacker News, When learning foreign languages, I made the most progress by speaking them throughout the day, every day. So I made a site where you can *speak* to an AI language teacher to practice both listening and speaking. # The product *What I have now:* * Multilingual speech recognition: You can ask a question in English and get an answer in your target language. * Feedback on your grammar. * Suggestions: See examples of what to say next to keep the conversation flowing. * Speed: Choose a lower speed for beginners or a faster one for advanced levels. * Translations: Click to see a…

Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…

I've built mandoBot, a web app that segments and translates Mandarin Chinese text. This is a Django API (using Django-Ninja and PostgreSQL) and a NextJS front-end (with Typescript and Chakra). For a sample of what this app does, head to https://mandobot.netlify.app/?share_id=e8PZ8KFE5Y. This is my presentation of the first chapter of a classic story from the Republican era of Chinese fiction, Diary of a Madman by Lu Xun. Other chapters are located in the "Reading Room" section of the app. This app exists because reading Mandarin is very hard for learners (like me), since…

We developed a new framework that enables flexible control of generated text in language models. By combining several models and/or system prompts in one mathematical formula, it lets you tweak your style and combine model outputs with ease. A handy tool for those working with LLMs, looking for more fine-grained control of stylistic output. More details in our paper: https://arxiv.org/abs/2311.14479. Feedback and potential applications are welcome.

Hi! I'm living as an expat in France and I had a hard time following the news. So I've been working on Fluentsubs that turns YouTube content into a language learning experience. YouTube videos up to 20 minutes can be transcribed and listened to. At the same time I made it easy to lookup certain words and automatically add spaced repetition cards using the given context. This means that you can also rehearse with a real voice and not with AI dubs. This works especially well for the somewhat smaller languages that have a small track on Duolingo, and now are desperately looking for content…

Hi HN! In trying to improve my Chinese skills, I built this tool that lets me write a mix of Chinese and English, then recommends a proper Chinese expression. This is super helpful when I want to write something in Chinese but I don't know all the vocab/grammar - I can enter my best effort and use English for the parts I don't know. Really, the fundamental benefit of the tool is that it encourages me to exercise the writing muscle, rather than defaulting to translating from English. My goal was to build something that is fast, relatively inexpensive, and not prone to misleading people.…
