In the grand tapestry of today's digital world, our service plays a critical role. As an intermediary, we provide an intuitive and efficient interface for leading text-to-speech service providers. This notable list includes giants like Google Text-to-Speech, Amazon Polly, IBM Watson Text-to-Speech, and Azure Text-to-Speech.
We pride ourselves on offering a streamlined experience, hiding the complexity of using these services under the hood. Yet, like any digital maestro, we are still subject to the limitations of our virtuoso performers.
Starting with Google, the majority of their voices reverberate at a sample rate of 24,000 Hz. However, there are three exceptions to the rule that resonate at a slightly lower frequency of 22,050 Hz. You can explore more about the voices Google offers HERE
On the other side of the tech globe, IBM Watson's voices serenade us at a consistent sample rate of 22,050 Hz. We have the freedom to specify diverse values, but IBM remains the maestro, deciding to up or downscale the sample rate rather than generating it afresh. Details of IBM's text-to-speech services
Our partners at Amazon play their part in the symphony, offering a range of sample rates, with the crescendo hitting at 24,000 Hz. In our pursuit of superior quality, we utilize the highest sample rates possible for each voice type. Details
Finally, Azure's voices stand as a testament to the highest audio fidelity, supporting an output of 48,000 Hz sample rate. We harness this power to its fullest, delivering voice outputs with a 48,000 Hz sample rate, 16-bit depth, and a single channel (mono).
Do note that for synthesized voices, stereo or 2-channel audio would be akin to a flamenco dancer performing a samba. There's simply no spatial information to capture in the stereo field. It's not their dance.
For each and every voice we serve, we ensure the use of the highest sample rates and bit depth that each provider can bestow. While we strive for higher sample rates, the current landscape of most platforms allows us only so much.
Once our digital orchestra concludes its performance, our service steps in to ensure the crescendo does not fade. The audio is encoded into an MP3 format during storage, with a keen focus on preserving the highest quality within these files. Rest assured, with us, your auditory experience is always in good hands.
