非会员标点保留

自建服务器在非会员的情况下,会自动把我模型给出的标点符号吃掉。你们的标点辅助功能,这个本身有点鸡肋吧,末尾自动加上句号,这个功能并不实用。不过,不至于在 试用期结束后,把自建模型产生的标点全部吃掉吧,吃掉以后几乎毫无实用性,只能开订阅或者会员?

期待有所改进吧。

Response from developer

嗨!真的很谢谢你花时间反馈,也谢谢你的耐心——你的建议对我们很有帮助 🙏 先给你吃颗定心丸:自建服务器一直是、以后也会一直是完全免费的,跟试用期没有任何关系,绝对不是付费墙。给你造成困扰,真的很抱歉。 简单说明一下自建模式:你的转写完全来自你自己的服务器,Diction 只是把服务器返回的文字原样插入,不做任何云端润色或标点处理。所以标点效果主要取决于你用的模型本身。 而自建最棒的一点,就是一切都由你掌控:你可以换一个标点更规范的模型,或者在你自己的服务器上接上你喜欢的 LLM + 提示词做后处理——Diction 会把结果原样呈现,风格完全按你的喜好来。 如果你愿意,我很乐意亲自帮你把它调到最顺手的状态:把你用的自建服务和 App 版本发到 support@diction.one,我会一步步陪你搞定。真的谢谢你选择自建、也谢谢你支持 Diction 🙏

Nice for da price!

. So um I have a problem typing at times my hands cramp I was uh born with a stroke, I know boo-hoo. The point is, is that um diction is affordable, rarely fails and is just reliable. And for someone like me I need that. So thank you, Diction.

Absolute amazing, secure, voice to text application!

I've been using this non-stop for two or three months now, and this is the exact application I wanted for this process. I wanted to be able to do it completely on device or through my own hosted voice transcription server, which this offers as well as extremely powerful. Or you can get really Powerful Third-party hosted solution that you can pay a small amount for. I'm extremely security and privacy conscious, so I wanted things I can control locally

The developer has added many new options over the months, including a newer model called NVIDIA Parakeet that is Is still extremely accurate, but smaller and significantly faster than the largest whisper model that was originally the best one in terms of accuracy.

This works extremely fast, even on device, on both my iPhone 17 Pro Max and my iPad Mini 7th generation (which uses the same CPU/SOC as the iPhone 15 Pro) which means it should be extremely fast on any modern iPhone or iPad.

Earlier versions had some minor bugs, but they have been fixed and the developer has been very responsive to the bug reports that I've made and they are working diligently to make this application better and better by day!

Better than Wispr Flow highly recommend

This app is truly incredible. It has all your bells and whistles and really great features that I really like and the local model Parakeet is very accurate. I used to be a Whisperflow user, and I just got sick and tired of having to context-switch and leave my app, and I feel like with this app, it's a lot more frictionless. Since the model locale you don't have to worry about your voice data being sent to a server if you just leave your microphone on all the time. I'm super satisfied with this app.

Perfect dictation even for my southern accent!

Works amazing. Especially on job sites with equipment running in the background. I'm using it now to leave this review. It looks very professional when texting with clients because it corrects my bad grammar and corrects some of my Southern accent. 10 out of 10 would recommend!
