API viability checklist
iSpeech: Endpoint test, format, latency, support and continuity must pass before integration.
- pricing · public range
- The API guide states $0.05 to $0.0001 per TTS word or ASR transaction depending on quantity for server/general platforms.
- evaluation · free
- The documentation provides a developer/demo-key path and mobile development sandbox; production web/server access requires credits or paid enablement.
- pricing · scenarios
- At the published extremes, 100,000 words would range from $10 to $5,000—too wide to budget from; a written quote is mandatory.
Endpoint test, format, latency, support and continuity must pass before integration.
Keep in mind: Use only the retained iSpeech evidence; do not generalize this decision asset to another product.Sources and verification date
