One-time Payments: What is it and why is it more beneficial than a subscription

, 31-07-2023

Dear SpeechGen users! We've noticed recently that many of you have questions about our payment system and the use of limits. "Is this a lifetime purchase?", "Do limits never run out?", "Will I receive my limits again at the start of the month?" These are just some of the questions you've been asking. We understand your doubts because the one-time payment system might seem new and unclear. But today, we want to clear up all your doubts and explain in detail how our system works and why it's so beneficial for you.

The Key Principles

A single payment is not a subscription. When you make a purchase on SpeechGen, you are buying a certain number of limits, not a subscription. This means you make a payment once and get a specific number of limits that you can use for speech synthesis.

We sell limits, not subscriptions. Why is this important? On many other services, you purchase a subscription that gives you access to speech synthesis for a month. But on SpeechGen, you buy as many limits as you need to convert text into speech.

Limits do not replenish automatically. In other words, the limits you purchase do not get renewed every month as they do with subscriptions. If you've used up all your limits, you simply need to buy a new package.

You can purchase limits many times in a row, without any restrictions. This means you can always buy more limits if you need them. When you purchase a new package of limits, the previous ones do not burn out; they simply add up.

Limits are like the internal currency of our service. You use them to turn text into speech, where 1 limit equals 1 character.

Limits won't disappear if you don't use them. You can buy the most expensive limit package for synthesizing 500,000 characters and not worry about having to use it within a month. This is the most cost-effective package, and you save 50%. Meanwhile, you can spend them slowly, for example, 65,000 characters per month. This is more beneficial than buying 65,000 characters every month.

But there is one condition - any package of limits needs to be used within a year. This is quite a long period, and it's beneficial for you.
