|---|---|---|
| Starting price | Free tier; paid tiers above The free tier has no downloads and no commercial rights. | From $30,000 / year Enterprise contracts start there and are scoped around call volume, concurrency, telephony setup, integrations, security needs and launch support. No self-serve tier is published. |
| Free trial | Free tier, without downloads or commercial rights | Not stated |
| Commercial use | Paid tiers only | Yes, under an enterprise contract |

| Hosting | Not stated | Cloud, with region-based hosting |
| Voice cloning | Yes, voice cloning to replicate a speaker | Cloning happens in ElevenLabs, not in Synthflow. The voice selector offers Synthflow's own TTS with twelve built-in voices and the ElevenLabs models from Turbo v2 and Flash v2.5 up to v3; a cloned or provider-specific voice is added through Imported > Import Voice by pasting the provider voice ID, or by connecting your own ElevenLabs API key so that account's custom voices appear in the selector. The vendor warns that a synthesiser model your own ElevenLabs plan lacks can mean lower quality or higher latency on your key |
| Real-time use | Yes, real-time voice agents (Falcon) | Yes, live inbound and outbound calls, with IVR handling for outbound agents, voicemail and silence handling, in-call SMS and WhatsApp messaging, and WhatsApp Business calling.

| Speech-to-speech and dubbing | Yes, Murf Dubbing localizes video into 40+ languages, keeping the original tone | Not documented. The voice documentation covers text-to-speech for live agents, with a speaker and a synthesis model chosen per agent, and carries no speech-to-speech conversion and no dubbing |
| Editing and controls | Pitch, speed and intonation controls, plus a custom pronunciation library | Flow Designer, a node-based canvas with conversation, message, branch, jump and custom action nodes, or a simpler prompt builder, plus a multi-agent system for several flows behind one agent, voice model and pacing settings, manual testing, automated simulations and custom evaluations that score calls against business goals |
| Consent and trust | Voices sourced through voice-actor partnerships; SOC 2, ISO 27001, GDPR and HIPAA compliant | SOC 2, HIPAA, PCI DSS, GDPR and ISO 27001, with encryption, audit logs and region-based hosting.

The trade-offs
Strengths and Limitations
Murf AI
Strengths
- Polished business voiceover
- Flexible for training and e-learning
- Also does real-time agent voices
Limitations
- Free tier has no downloads or commercial rights
- Less storytelling realism than ElevenLabs
Synthflow
Strengths
- No-code Flow Designer with a multi-agent system, so a non-developer can build and change call flows
- Connects to existing telephony and contact centre stacks over SIP, including Genesys, Avaya, Five9, Cisco and RingCentral
- White-labelled deployments for partners reselling voice agents under their own brand
- SOC 2, HIPAA, PCI DSS, GDPR and ISO 27001, with agent-level retention and PII redaction controls
Limitations
- No self-serve or trial tier is published; the only listed plan is an enterprise contract from $30,000 per year
- Pricing is scoped by sales, so the cost of a given call volume is not knowable from the website
- Latency figures differ between the vendor's own pages, so the published number is not a specification to rely on
- A cloned voice has to be created in a separate ElevenLabs account and imported, so it means a second subscription alongside Synthflow
