How to choose a Slang.ai alternative
- Test with real Indian callers and real background noise. Accent and code-mixing handling is where most global vendors underperform.
- Measure latency yourself. Above roughly a second of silence, callers start talking over the agent and the conversation falls apart.
- Check consent and recording compliance for outbound calling, including DND rules, before you scale a campaign.
