Frequently Asked Questions
Have questions before choosing? Here are the answers to common queries.
Yes, absolutely. There are no lock-in contracts. You can upgrade to a higher tier instantly from your dashboard or switch between monthly and annual cycles. When upgrading mid-cycle, unused credits are pro-rated towards your new plan.
In spoken Hindi, 1,000 words average roughly 6 to 7 minutes of natural paced speech. For instance, the Starter tier's 300,000 words delivers approximately 300 minutes (5 full hours) of studio-quality synthesized speech every single month.
Yes! All paid tiers (Starter, Pro, Business, and Enterprise) grant full commercial broadcasting and monetization rights. You retain 100% ownership of your generated audio. Only the Free tier is restricted to personal, non-commercial testing.
Once your quota is reached, speech synthesis will pause until your next monthly renewal. You can purchase instant credit top-up packs or upgrade to the next plan at any time without waiting for the billing cycle to end.
For Enterprise customers, our acoustic AI engineers train a dedicated neural checkpoint using 30 to 60 minutes of studio audio recorded with your brand voice actor. The resulting custom voice model is private, secure, and exclusively accessible to your organization.
We support all major Indian payment channels including UPI (Google Pay, PhonePe, Paytm), NetBanking, Debit/Credit Cards, and international corporate cards. GST invoices with input tax credit (ITC) are automatically generated for all business purchases.
