Common questions about choosing a TTS provider
ElevenLabs consistently ranks highest for voice naturalness and emotional range. However, Google WaveNet and Azure Neural are very close behind and offer excellent quality at lower costs. For most business use cases, all three are more than sufficient.
Google WaveNet and Cartesia offer the best value for high-volume usage. Google is about 50% cheaper than ElevenLabs with comparable quality. Cartesia is the most budget-friendly but with slightly lower quality.
Google has the broadest Indian language support (Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Marathi). Azure also has good coverage. ElevenLabs focuses more on major global languages but has excellent Indian English voices.
Cartesia has the lowest latency (under 150ms), followed by ElevenLabs (around 200ms). For real-time voice bots where conversation flow matters, these two are recommended. Google and Azure are slightly slower but still acceptable.
Yes, our platform supports configuring different TTS providers per agent. You could use ElevenLabs for sales calls (premium quality) and Google for order status updates (cost-effective). Switch providers anytime without code changes.
ElevenLabs offers the most advanced voice cloning - you can create custom voices from audio samples. Azure also supports custom voice training but requires more samples. Google and OpenAI currently don't offer voice cloning.
For customer support, we recommend Google WaveNet or Azure Neural. They offer warm, professional voices at reasonable costs. If budget allows, ElevenLabs provides the most empathetic-sounding voices.
