51 分•作者: mariano54•6 个月前
大家好，我们是 ISSEN（<a href="https://issen.com">https://issen.com</a>）的 Mariano 和 Anton，这是一款外语语音辅导应用，可以根据您的兴趣、目标和需求进行个性化调整。
演示：<a href="https://www.loom.com/share/a78e713d46934857a2dc88aed1bb100d?sid=ec4dc1f3-1a4f-4d75-8e87-efbb3d2b2e90" rel="nofollow">https://www.loom.com/share/a78e713d46934857a2dc88aed1bb100d?...</a>
我们创办这家公司的初衷是，在寻找练习日语和法语口语的优秀工具时遇到了困难。虽然有导师很棒，但也有一些缺点：他们可能很贵（因为按小时收费），很难预约，而且前期成本很高（找到你喜欢的导师通常需要试用几个你不喜欢的）。
我们想要一个能和我们对话的工具——真实地进行完整的对话——并且真正帮助我们提高。所以我们自己开发了它。
这款应用依赖于一个定制的语音 AI 流程，结合了 STT（语音转文本）、TTS（文本转语音）、LLM（大型语言模型）、长期记忆、打断、轮流对话等技术。让语音转文本对学习者来说效果良好是最难的部分之一——尤其是在有口音、多语言句子和嘈杂环境的情况下。我们现在结合了 Gemini Flash、Whisper、Scribe 和 GPT-4o-transcribe，以最大限度地减少错误并保持对话流畅。
我们不想过多地关注游戏化。根据我们的经验，这会导致用户在应用中表现良好，实现长期连胜等等，但实际上并没有让你想要学习的语言变得流利。
使用 ISSEN，您可以立即开始用该语言进行对话和沉浸式学习，虽然这并不容易，但却是一种更有效率的学习方式。
我们将此与单词库和 SRS 抽认卡相结合，用于在 AI 语音聊天中学习的新单词，这可以快速提高词汇量和口语技能。我们还根据每个学生的目标、兴趣和偏好创建定制课程，以及完全可定制的设置，如语速、轮流对话、正式程度等。

定价：20 分钟免费试用，每月 20-29 美元（取决于时长和具体地区）
我们希望得到您的反馈——关于技术、用户体验，或者您希望从这样的工具中获得什么。谢谢！

Hey HN, we're Mariano and Anton from ISSEN (<a href="https://issen.com">https://issen.com</a>), a foreign language voice tutor app that adapts to your interests, goals, and needs.<p>Demo: <a href="https://www.loom.com/share/a78e713d46934857a2dc88aed1bb100d?sid=ec4dc1f3-1a4f-4d75-8e87-efbb3d2b2e90" rel="nofollow">https://www.loom.com/share/a78e713d46934857a2dc88aed1bb100d?...</a><p>We started this company after struggling to find great tools to practice speaking Japanese and French. Having a tutor can be awesome, but there are downsides: they can be expensive (since you pay by the hour), difficult to schedule, and have a high upfront cost (finding a tutor you like often forces you to cycle through a few that you don’t).<p>We wanted something that would talk with us — realistically, in full conversations — and actually help us improve. So we built it ourselves.
The app relies on a custom voice AI pipeline combining STT (speech-to-text), TTS (text-to-speech), LLMs, long term memory, interruptions, turn-taking, etc. Getting speech-to-text to work well for learners was one of the hardest parts — especially with accents, multi-lingual sentences, and noisy environments. We now combine Gemini Flash, Whisper, Scribe, and GPT-4o-transcribe to minimize errors and keep the conversation flowing.<p>We didn’t want to focus too much on gamification. In our experience, that leads to users performing well in the app, achieving long streaks and so on, without actually getting fluent in the language you're wanting to learn.<p>With ISSEN you instantly speak and immerse yourself in the language, which, while not easy, is a much more efficient way to learn.<p>We combine this with a word bank and SRS flashcards for new words learned in the AI voice chats, which allows very rapid improvement in both vocabulary and speaking skills. We also create custom curriculums for each student based on goals, interests, and preferences, and fully customizable settings like speed, turn taking, formality, etc.<p>App: <a href="https://issen.com">https://issen.com</a> (works on web, iOS, Android)
Pricing: 20 min free trial, $20–29/month (depending on duration and specific geography)<p>We’d love your feedback — on the tech, the UX, or what you’d wish from a tool like this. Thanks!
