I built a fully offline text to speech Mac app because cloud TTS annoyed me [Giveaway: 5 Lifetime Licenses]

Full contextOriginal content · Reddit

Hey r/MacApps, I’m Tarun Yadav, an indie developer and the maker of Murmur. You can find me on LinkedIn or email me at tarunyadav9761@gmail.com. Murmur also has a Privacy Policy and Terms of Service if you want to check those before downloading. Why I built it Most AI voice tools are good at generating a short clip. Things get messy when the script becomes 20 pages long, has multiple speakers, or needs several corrections. You end up with loose audio files, inconsistent voices, repeated uploads and a credit meter running every time you fix a sentence. I wanted a native Mac workspace where I could keep the script, speakers, voices, generated clips and final export together. How Murmur is different Murmur runs speech models locally on Apple Silicon. After the required models are downloaded, your scripts and generated audio can stay on your Mac. There is no monthly subscription or generation credit system. The app costs $49 once. Murmur currently supports several local voice workflows, including fast preset narration, voice cloning, multilingual speech, expressive delivery and creating voices from written descriptions. What you can use it for Turn scripts into YouTube or product-demo voiceovers Create audiobook and course narration drafts Import PDFs and EPUBs Clone a voice from a short recording Design a reusable voice by describing it Assign different voices to multiple speakers Regenerate one bad line without redoing the full script Queue longer generation jobs Organize scripts and clips inside Projects Export finished audio as WAV or M4A It includes 860+ community voices, along with local models such as Kokoro, Qwen3-TTS, Chatterbox and Fish Audio. A practical caveat: Murmur requires an Apple Silicon Mac and macOS 14 or later. Some optional models are several gigabytes and need an initial download. Voice cloning, language support and expression controls also vary by model. Pricing $49 one-time, with no recurring subscription or character credits. There is no free trial, but purchases have a seven-day refund period. Murmur: https://www.murmurtts.com Giveaway: 5 lifetime licenses Comment with one specific way you would use Murmur.

Love to try, I´m currently using VoiceBox, OpenVox and Speallone how murmurr compare to these ones?, especially in the ability to change expression during the narration

u/tarunyadav9761OPReply

The biggest difference is that Murmur is built around longer production workflows: scripts, multiple speakers, generated clips, timeline editing and final export stay together inside a Project. Expression control depends on the model. Fish Audio supports detailed inline directions such as whispering, changing pitch or adding pauses. Chatterbox Turbo supports reaction tags such as [laugh], [chuckle] and [cough]. Qwen Voice Design lets you describe the kind of voice you want, while Kokoro is intentionally simpler and faster. You can change delivery between lines or sections, but Murmur doesn’t currently have a DAW-style expression curve that you draw across a clip. If that is the kind of control you use in the other apps, I’d be interested to hear how you use it.

27 messages asking for a free code and 12 upvotes on the post... 😂 If you're going to ask something for free, the least you can do is upvote the damn post!

it's a giveaway bro, what's wrong with it?

u/TrevorTheTrevorReply

Just show some appreciation to OP, it only takes a click to you but means more to them and gives their post more visibility

49 is steep price, what does this offer over the likes of 'TypeWhisper'?

u/tarunyadav9761OPReply

TypeWhisper is actually a speech-to-text and dictation app, while Murmur goes in the opposite direction: it turns scripts and documents into generated audio. They’re useful together, but they don’t really replace one another. Murmur’s price covers multiple local TTS models, 860+ voices, voice cloning, Voice Design, PDF/EPUB import, multi-speaker Projects, generation queues, timeline editing and WAV/M4A export. There are no generation credits or recurring fees. That said, if someone only needs basic macOS read-aloud, Murmur would probably be more than they need.

u/tarunyadav9761OPReply

Voice cloning runs locally on your Mac. You provide a clean reference recording, add its transcript when the selected model requires one, and Murmur generates speech using that voice without uploading the sample. Qwen3-TTS is a good general starting point, while Chatterbox is useful when you also want more expressive delivery. The cloned voice can be saved and reused in future scripts or assigned to a speaker inside a Project. A quiet, single-speaker recording without music, reverb or background noise will give you the best result. And, of course, only clone voices you own or have permission to use.

TTS is a big use case here as I am always reading something. How much memory does this use running models for TTS and is there a delay as it generates?

Here's my comment from a few months ago. We also spoke via DM. Still happy to try this out. Always on the lookout for something new in this space. I also have two ADHD kids who I like to challenge with new types of tools, to see what fits their learning style best. r/macapps ·7 mo. ago I built a fully offline text to speech Mac app because cloud TTS annoyed me [Giveaway: Lifetime Promo Codes] -Internet-Elder-·7 mo. ago Hi. I'm the guy who has commented numerous times wondering why there are so many speech-to-text apps, and not enough text-to-speech apps. I'd be happy to try this out for you. Automator used to be able to do this well, and of course for free, but a few years ago it all of a sudden saw limits on file length and number of words. You could no longer do long passages or books. To this day I'm always speaking up and on the lookout for a worthy solution that does what the OS used to do.

TTS will most certainly for public speaking and presentation practices!

u/DeLiMG

I might use it to listen to books, and I hope that is possible. If it is, I would like to get a code.

u/Stubborninmate

Import pdf and ebub wow !! That's something which is to die for

u/tagtech414

I've been looking for something like this! Would love a license, please! Thank you Main use case would be to type instructions for training procedures and have it read aloud over screen recordings and screen shots

u/seriousstuffonly_71

I'd probably use it for educational purposes, most likely for math videos

u/nez329

Sometimes, I find I learn better by listening rather than reading. Hope to use Murmur to turn long articles into audio, narrated in a voice like Tony Stark’s J.A.V.I.S. This way, learning becomes more engaging and immersive, almost like stepping into Iron Man’s world which helps me remember and understand the material much better. Hope to be selected.
