Azure

Azure's TTS service stands out due to its support for SSML, enabling precise customization of voice outputs. Key features include:

Voice Selection

Azure's vast voice library enables you to find the ideal voice that best represents your bot's identity and connects with your target audience.

The expressiveness of the voices can vary based on their age. Check out the documentation to identify which voices are the newest to find the best voice in your language. Do not shy away from trying a multilingual voice from a different language, and enforcing a language through the lang tag in the SSML template.

Language Adaptability

Whether your project requires different voices for various languages or a single voice capable of handling multiple languages, Azure provides the versatility needed. Additionally, various dialects per language allow for even more precise customization to match your audience's linguistic and cultural nuances.

Prosodic Controls

Enhance the delivery of your voice outputs by adjusting parameters such as speech rate, pitch, and contour. This allows for the expression of emotions or the emphasis of certain message parts.

Latency

Very low, typically between 200–300 ms, providing quick response times during conversations.

Parloa offers an advanced voice latency reduction strategy for these voices by utilizing multiple processing regions per geography (not applicable to preview voices).

Availability & Pricing

Available to all users and included in standard pricing.

Processing Regions

Regional processing is available in both the US and the EU. The service does not retain any traces of inputs or outputs.
