Disclosure: I make RBS Voice Cloner V2. I'll be honest about where Murf and Speechify are still better choices for specific use cases.
These three tools come up together a lot in "best AI voice software" Google searches, but they're solving different problems. Murf is a polished web-based voiceover studio aimed at marketing and e-learning teams. Speechify is primarily a "read-this-article-to-me" accessibility tool with a strong mobile presence. RBS Voice Cloner V2 is a free local Windows app focused on voice cloning. Picking the right one depends entirely on what you're actually trying to do.
The 30-second answer
- You want polished marketing voiceovers with timeline editing, music tracks, and team collaboration: Murf AI.
- You want to listen to articles, books and PDFs in a natural voice while you commute or do chores: Speechify.
- You want to clone a specific voice (yours, public-domain, with permission) and generate unlimited audio for free: RBS Voice Cloner V2.
- You're doing audiobook drafts and don't want to bleed credits: RBS Voice Cloner V2.
What each one actually is
Murf AI
Web-based voiceover studio launched in 2020. Around 200 stock voices across 20+ languages. The unique strength is the timeline editor — you write your script, drop voice clips on a timeline alongside background music and sound effects, fine-tune emphasis and pauses, export a finished audio file ready for video. Aimed at corporate training, e-learning, marketing video voiceovers, podcast intros.
Pricing tiers (as of April 2026): Free (limited download minutes), Creator ~$29/month, Business ~$66/month, Enterprise custom. Voice cloning is on the higher tiers and is more limited than ElevenLabs — Murf's strength is studio voices, not cloning.
Speechify
Started as "read articles aloud" Chrome extension; now a multi-platform app for Windows, Mac, iOS, Android plus the browser extension. Different positioning from Murf — Speechify is for consuming long-form content with your ears (textbooks, articles, PDFs, emails) rather than producing audio for distribution. Voice library is smaller but the natural narration quality is excellent.
Pricing tiers: Free (limited voices, slower speeds), Premium ~$11.66/month annual ($139/year). They've also rolled out voice cloning in the higher tiers.
RBS Voice Cloner V2
Free Windows desktop app built on the open-source XTTS v2 engine. 16 built-in voices. Unlimited custom voice cloning from a 30-second sample. 17 languages with built-in auto-translate. 7-band parametric EQ. Redesigned audio editor. Runs fully offline after the first model download (~2 GB, one time).
Pricing: free, forever. ~2 GB download because PyTorch + CUDA runtime are bundled in the installer to skip the Python setup pain.

Where Murf is genuinely better
- Marketing video voiceovers. The timeline editor with background music tracks and sound effects is excellent. RBS Voice Cloner doesn't compete here — you'd export the voice from RBS and then mix in DaVinci Resolve or Audition, which is a workflow not a one-stop solution.
- Stock voice variety. 200+ studio voices means you can find a tone you like for a specific brand. RBS Voice Cloner has 16 built-ins plus your custom clones — fewer "off the shelf" options.
- Team collaboration on scripts. Real shared workspaces, comment threads, version history. RBS Voice Cloner is single-user.
- Sub-second generation. Cloud has a real latency advantage if you're iterating on a voiceover and rendering 50 takes per minute.
Where Speechify is genuinely better
- "Read this article to me" workflow. Browser extension, mobile app, PDF import, OCR for scanned documents. RBS Voice Cloner doesn't do this — you'd have to copy text and paste it into the app, which is friction Speechify doesn't have.
- Cross-device sync. Start a book on your laptop, finish on your phone, picks up where you left off. Speechify nails this.
- Variable playback speed (up to ~5x for speed-listeners). Built around comfortable consumption.
- Mobile. If iOS / Android matters, RBS Voice Cloner doesn't exist there.
Where RBS Voice Cloner V2 is genuinely better
- Voice cloning, real and unlimited. 30-second sample, save unlimited profiles, generate forever. Murf and Speechify gate cloning behind higher tiers and have stricter limits.
- Cost at volume. Audiobook authors generating 80,000+ words per month would pay $30-100 in Murf or Speechify credits. RBS Voice Cloner: $0.
- Complete data ownership. Voice samples, voice profiles, generated audio all stay on your PC. For people uncomfortable uploading their voice to a cloud service, this matters.
- No subscription, ever. One install, free forever. No "service shutting down in 60 days" risk.
- Works offline. Plane, train, no internet — RBS Voice Cloner keeps working. Murf and Speechify (mostly) don't.
Honest cost math at three usage levels
Light user — 5,000 words / month (occasional voiceover):
- Murf free tier: doable but limited downloads/month.
- Speechify free tier: doable for consumption, not creation.
- RBS Voice Cloner: free.
Active creator — 30,000 words / month (regular podcast or YouTube voiceover):
- Murf Creator $29/mo = $348/year.
- Speechify Premium ~$140/year (for narration use).
- RBS Voice Cloner: free.
Audiobook narrator — 80,000 words / month:
- Murf Business $66/mo = $792/year.
- Speechify Premium $140/year (limits may bite).
- RBS Voice Cloner: free.
The cost equation tilts more heavily toward free local tools the more audio you generate. For light users with light needs, the paid tools' polish is often worth it. For heavy users, free is hard to argue with.
Quality — honest take
Murf's stock voices are studio-quality with subtle emotional range. Speechify's narration voices are excellent for long-form listening — they're tuned for comfort over hours, not impressiveness in 5-second clips. RBS Voice Cloner V2 (XTTS v2 underneath) is genuinely competitive with both for most everyday use. Where the open-source side still trails: very short ad reads where every word needs maximum punch, or specific emotional deliveries (whisper, surprise, anger) that the closed services have specifically tuned.
For long-form content (podcasts, audiobooks, narration) — the gap is small. For short-form punchy content (ads, intros) — paid tools still have an edge.
Quick-pick recommendation
Marketing / corporate / e-learning team producing branded video voiceovers: Murf. Worth the subscription for the timeline editor.
You read a lot and want to listen to articles / books on the go: Speechify Premium. Worth the $140/year if you're a heavy reader.
Indie creator, audiobook author, language learner, anyone cloning their own voice: RBS Voice Cloner V2. Free, offline, unlimited.
You're not sure: install RBS Voice Cloner V2 first — it's free and reversible. If after a month you're hitting walls (you wanted Murf's timeline editor; you wanted Speechify's article reader), you've lost nothing. Pay for the polish you actually need.
