Common questions about speech-to-text and text-to-speech pricing
AssemblyAI ($0.0054/min) and Deepgram ($0.0059/min) offer the lowest per-minute rates for high-quality STT. OpenAI Whisper API is also competitive at $0.006/min but doesn't support real-time transcription. For Indian languages specifically, Google Speech-to-Text offers the best balance of cost and language coverage.
Google Speech-to-Text and Azure Speech have the widest Indian language support with Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, and Urdu. Deepgram has Hindi, Bengali, and Tamil in beta. AWS Transcribe supports Hindi, Tamil, Telugu, Marathi, and Gujarati.
Google Cloud TTS and Amazon Polly offer the lowest rates at $0.004/1K characters for standard voices, and $0.016/1K for neural/WaveNet voices. However, ElevenLabs ($0.18-0.30/1K chars) offers significantly more natural-sounding voices if quality is the priority.
ElevenLabs produces the most natural-sounding speech and offers voice cloning, which no other provider matches in quality. For customer-facing voice AI where natural conversation matters, the premium is often justified. For IVR or notification use cases, Google/AWS Neural voices work well at lower cost.
For 10,000 minutes of voice AI per month, expect: $100-400 using Google/Azure (STT + TTS), $240-360 with Deepgram + ElevenLabs for premium quality, or $280-400 with AWS. Edesy's all-inclusive plans start at $199/month including STT, TTS, AI processing, and telephony.
Watch for: 1) Per-request fees in addition to per-minute/character costs, 2) Data transfer fees (especially AWS), 3) Different rates for real-time vs batch processing, 4) Premium rates for specific languages or voices, 5) Minimum monthly commitments, 6) Costs for model training/customization.
For real-time applications, Deepgram leads with ~300ms STT latency. Amazon Polly offers ~150ms first-byte TTS latency. ElevenLabs streaming API has improved to ~500ms. Google and Azure both offer good real-time performance around 200-400ms for both STT and TTS.
Yes! Many voice AI implementations use different providers for STT and TTS based on their strengths. A common combination is Deepgram for fast STT + ElevenLabs for natural TTS. However, managing multiple vendors adds complexity. Platforms like Edesy abstract this by providing a unified interface to multiple providers.
