Voice correction for clearer, more understandable speech
DysVoxa is a desktop voice correction app for Windows and Linux that helps people with dysarthria and other speech impairments be understood. Speak naturally, and DysVoxa corrects and improves your speech into clearer spoken output - all on your own computer, with nothing sent to the cloud.
Voice improvement that helps you be understood
If you have dysarthria - from stroke, Parkinson's, ALS, ataxia, cerebral palsy, or another condition - you know what it's like when people can't understand you. DysVoxa gives you a voice correction tool to make your speech clearer and more understandable, on your terms.
You stay in control
You decide when to record each phrase. No continuous listening, no always-on microphone.
Your voice stays private
Everything runs on your PC. No audio is ever sent to a server. Your biometric voice data is yours alone.
Works where you need it
Output goes to your speakers or a virtual microphone - use it in Zoom, phone calls, or face-to-face.
What using DysVoxa feels like
Using DysVoxa is simple. Here's what a typical interaction looks like:
1. You speak
Press record, say your phrase naturally, then stop. You control the timing completely.
2. It understands
DysVoxa transcribes what you said - on your computer, not in the cloud.
3. It corrects
If the transcription has errors, DysVoxa applies speech correction locally to improve clarity before speaking it.
4. It speaks clearly
A clear, understandable synthesized voice speaks your corrected words - through speakers or directly into calls.
What to know before trying it
- DysVoxa is currently a Windows and Linux desktop beta, not a phone app.
- It works one phrase at a time; you decide when to record and when to stop.
- Voice correction depends on speech recognition, which is not perfect, especially with severe speech difficulty or noisy rooms.
- Keep another communication method available for urgent or safety-critical situations.
For caregivers and family
If you support someone with dysarthria, you've seen the frustration: repeating themselves, being talked over, avoiding conversations. DysVoxa can help the person you care for:
- Stay in phone calls and video chats without the exhaustion of constant repetition
- Speak for themselves in medical appointments, rather than having someone else answer
- Participate in group conversations where fast turn-taking normally leaves them behind
- Maintain independence in communication - on their own computer, with their own voice
DysVoxa is not a replacement for human connection. It's a tool that helps the person you care about stay connected on their own terms.
Why on-device voice correction matters
Many speech correction tools send your voice to the cloud. DysVoxa doesn't.
- Speech recognition runs entirely on your PC - just on your computer, not in the cloud
- Your voice recordings never leave your device
- No account required for core features
- No telemetry or tracking in the current beta
- Works offline - no internet connection needed for voice correction and speech improvement
Hardware requirements
Because all speech recognition and correction run locally on your computer, hardware matters. Below the minimum specs, you will still get results - but with higher latency and slower processing.
CPU: 4 cores / 8 threads
A multi-core processor is needed for real-time speech recognition and correction. Fewer cores will work but produce higher latencies.
RAM: 16 GB minimum
Local speech models need memory. With less than 16 GB, processing slows down and latency increases noticeably.
Below these specs DysVoxa may still function, but expect higher latencies and slower correction. A modern 4-core/8-thread CPU with 16 GB RAM is the practical floor for usable real-time results.
Who DysVoxa is designed for
DysVoxa's voice correction is designed for dysarthria from any cause, and for other situations where speech clarity and intelligibility are affected by illness, injury, surgery, medication, or medical treatment:
- Dysarthria from stroke
- Parkinson's disease
- ALS (amyotrophic lateral sclerosis)
- Cerebral palsy
- Ataxia (including spinocerebellar ataxia)
- Traumatic brain injury (TBI)
- Multiple sclerosis
- Speech affected by medical treatments or surgery
- Other motor speech conditions that make speech hard to understand
