# Cepstral review (2026): is it worth it? > Desktop and phone-system text-to-speech voices and engines Checked Nov 13, 2026 ยท graded Nov 13, 2026 by ToolGPA. Cepstral is a Pittsburgh company that makes only text-to-speech software. Its Personal voices install on a Windows, Mac or Linux computer and read email, documents and apps aloud, and its Telephony products serve speech to phone and IVR systems over standard protocols. Prices are set in a separate store that requires an account. - **Category:** AI Voices & Text to Speech - **Made by:** Cepstral, LLC - **Website:** https://www.cepstral.com - **Runs on:** Windows, macOS, Linux - **Who should skip it:** Skip it if you want a price before buying, as none is shown publicly. - **Facts last checked:** Nov 13, 2026 ## Pricing Cepstral's current pricing could not be confirmed from its own site. ## Key features - **Personal voices:** Voices for desktop use that read email, documents and any speech-enabled app aloud, with optional Speech FX filters such as Old Robot. - **Windows SAPI support:** On Windows the voices are Microsoft SAPI compatible, so they show up in the system's text-to-speech settings as a replacement for stock voices. - **Swift command-line engine:** Every voice ships with the Swift engine, which can speak text or files from the command line or save the audio to a file. - **Telephony 6:** A server product for phone systems that follows MRCP v1 and v2 and VoiceXML, for reading prompts and information to callers. - **Lightweight engine:** The company says its engine runs in a small memory footprint, on handheld devices or in several instances on a server. ## Good for - Users who want a local, installed voice for reading documents - Phone-system builders needing MRCP or VoiceXML speech - Command-line and Linux users who script speech output ## Worth knowing - Prices are not shown on its public pages; the store needs an account and returned an access error without one. - Personal voices are for personal use only and are not licensed for distributing the audio; a separate audio license is quoted by sales. - The Mac page lists support only for Mac OS X 10.6 to 10.8, and the Windows page lists XP through Windows 10. - Linux personal voices are bought by opening a support ticket describing your use. ## ToolGPA grades **GPA: 1.4 out of 4**, graded Nov 13, 2026.

The category's chart of price against score: https://toolgpa.com/charts/ai-voices ## Keep it, or make your own? **Keep it.** To replace Cepstral you would be making a voice model, which you can rent by the minute but not make. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 71 of the 72 other AI voice generators grade higher. - You could not: A voice model, which you can rent by the minute but not make. - You could not: Phone numbers and calls carried over the phone network. - You could not: Apps for macOS, Windows and Linux that stay in step with each other.
