Frequently Asked Questions

How easy is it to switch from OpenAI Text-to-Speech to Unreal Speech?
  • Very easy, it only takes a few minutes. We give you 250,000 free characters per month, so you can start using our simple text-to-speech API right away.
 How does the feature set of Unreal Speech compare to that of OpenAI Text-to-Speech?
  • Unreal Speech offers several features not available in OpenAI Text-to-Speech, including per-word timestamps, pitch control, speed control, and support for phone formats like pcm_mulaw.
  • These features enhance customization and integration capabilities, particularly for detailed audio editing and telephony applications.
  • Conversely, OpenAI Text-to-Speech's standout feature is its multilingual support, which Unreal Speech does not offer, making OpenAI's solution more versatile for global applications.
 For startups and developers with variable text-to-speech needs, which service would you recommend between Unreal Speech and OpenAI Text-to-Speech?
  • For startups and developers with variable needs, the choice depends on specific requirements.
  • If multi-language support is key, OpenAI Text-to-Speech is the better option.
  • However, for those needing detailed control over voice output, such as pitch and speed adjustments, or applications requiring per-word timestamps, Unreal Speech would be the recommended choice due to its extensive feature set and flexible pricing tiers.
 How does the cost of OpenAI Text-to-Speech compare to Unreal Speech for a similar amount of characters?
  • OpenAI Text-to-Speech operates on a Pay As You Go model at $15 / $30 per 1M characters, which doesn't directly compare to any Unreal Speech tier.
  • However, for substantial usage, Unreal Speech offers more characters for the price at higher tiers, such as the Pro plan at $1499/mo for 150M characters, suggesting better scalability for heavy users.
 For a user needing phone format compatibility (e.g., pcm_mulaw), which text-to-speech service would you recommend?
