Altered Real-Time Pro

Altered Real-Time Pro is a desktop virtual microphone that applies AI voice processing to speech sent into communication apps. It best suits callers who want to improve speech, change vocal identity or translate accents in real time. Its tiered plans make the main trade-off clear: modest daily limits at the low end, broader features and unlimited processing at higher prices, with different privacy terms for discounted plans.

Overview

The virtual microphone routes processed audio to any app that accepts microphone input, including Zoom, Google Meet, Discord, Skype, WhatsApp, games and call-centre software. That broad compatibility makes it useful across work calls and gaming without being tied to one communication service. It runs on macOS and Windows, so it is not a fit for people seeking a mobile app.

Key features

• Isolate suppresses noise and competing speakers, a practical choice for making speech clearer in busy audio environments.
• Voice Skins change vocal identity. The free plan includes four skins each day; the $5 plan unlocks all of them.
• Accent Translation changes accents, a specialized capability included in Call Center plans rather than the entry Voice Skins tier. Its effects are designed around 135 ms of algorithmic latency, but actual delay varies with the model, CPU, audio settings and processing cores.
• Euphonia is aimed at restoring voices affected by dysphonia and voice disfluencies. It is reserved for Euphonia plans.

Local compute processes audio on the user's machine, and voice data stays on the PC. Cloud Compute can instead offload work to nearby Altered servers in the US, EU or India. That flexibility comes with an additional charge and a different processing path; Cloud Compute costs $2 per hour of daily quota per month.

Pricing

Altered Real-Time Pro is freemium. The free tier is a useful way to try speech enhancement and a small rotating selection of Voice Skins, but 20 minutes of processing per day limits sustained use. It also includes multi-seat account management.

• Voice Skins — $5 a month, billed monthly (excl. tax): 120 minutes of daily processing, all Voice Skins, all Isolate models and multi-seat account management. This is the sensible step up for regular callers who do not need Accent Translation or Euphonia.
• Call Center (discounted) — $8 a month, billed monthly (excl. tax): unlimited processing, Accent Translation models, all Isolate models, all Voice Skins and multi-seat account management. The lower price comes with consent to use anonymized voice data to improve AI models.
• Euphonia (discounted) — $8 a month, billed monthly (excl. tax): unlimited processing, Euphonia models for dysphonia and voice disfluencies, all Voice Skins, all Isolate models and multi-seat account management. It has the same discounted-plan data consent.
• Call Center — $12 a month, billed monthly (excl. tax): unlimited processing, Accent Translation models, all Isolate models, all Voice Skins and multi-seat account management. It costs more than the discounted option but does not carry that plan's stated consent term.
• Euphonia — $12 a month, billed monthly (excl. tax): unlimited processing, Euphonia models, all Voice Skins, all Isolate models and multi-seat account management, without the discounted plan's stated consent term.
• Enterprise — custom pricing, per seat: all Accent Translation models, all Voice Skins, priority support, usage analytics, SLA-backed uptime, and on-device or on-premise BYOC compute; Altered-hosted compute is also available. Enterprise input languages include Indian-English, Filipino-English, LATAM-English, Slavic-English and African-English. Team invitations, seat assignment, usage charts, billing controls and version management make this the tier for organizations that need administration and support.

Standard subscriptions state that voice data never leaves the device. Discounted subscriptions trade that term for a lower price and consent to anonymized data use for AI improvement. The privacy policy says the company uses commercially acceptable means to protect personal data but cannot guarantee absolute security.

Platforms

The app supports macOS and Windows desktop systems. Realtime processing and virtual-microphone routing suit live calls and games, but actual latency depends on the chosen model and the machine's audio and compute setup.

Who it's for

Choose it if you need voice processing across multiple microphone-enabled apps, especially noise and competing-speaker suppression, voice changes, accent translation or Euphonia restoration. The free tier suits occasional use; frequent callers who only want Isolate and Voice Skins can consider the $5 plan. Accent translation and voice restoration require higher tiers, while Enterprise is geared to managed teams. Look elsewhere if you need mobile support or do not want discounted plans' anonymized-data consent.

Pros and cons

Pros

• Works across many communication apps: microphone-input compatibility makes it useful beyond a single meeting or gaming platform.
• Distinct processing options: noise suppression, voice identity changes, Accent Translation and Euphonia address different speaking needs.
• Local processing option: standard subscriptions state voice data stays on the device, a meaningful advantage for privacy-conscious callers.
• Clear upgrade path: the $5 tier expands daily processing and skins, while $12 plans add unlimited processing and specialized models.

Cons

• Free use is tightly capped: 20 minutes per day and four Voice Skins each day can constrain regular callers.
• Specialized features cost more: Accent Translation and Euphonia are not included in the $5 plan.
• Discount pricing has a data trade-off: the $8 specialist plans require consent to anonymized voice-data use for model improvement.
• Latency is not fixed: the 135 ms design target for accent-changing effects does not guarantee the same delay across systems.

Verdict

Altered Real-Time Pro is a strong fit for desktop callers who want several kinds of live speech processing routed into their existing apps, particularly when noise suppression or a specialized voice model is central to the choice. Its best argument is the combination of broad microphone compatibility and focused tools; its key drawbacks are the free daily cap and the privacy concession on discounted specialist plans. Choose a standard paid tier when on-device voice-data terms matter, and look elsewhere if you need mobile support or a broader free allowance.
