The advanced AI engine within Echo is designed to provide extremely high accuracy when transcribing text.
To ensure you get the best accuracy possible, there are several steps you can follow.
When you load Echo, it will automatically choose an audio input device on your computer to use. This may not initially be the device you wish to use with Echo. Microphones can differ greatly in the sound quality which they provide, which will lead to differences in the accuracy Echo can produce. Additionally, if you are speaking into one microphone, but the sound it being picked up by another, this will also impact the sound quality which Echo is receiving.
It’s important to ensure that the correct microphone is selected.
Click on the icon in the top left corner of Echo and open the Settings from the dropdown menu.
Use the arrow under ‘Preferred Audio Input Device’ to choose the microphone you wish Echo to use. This could be a handheld microphone, a headset or a built-in microphone on a laptop.
You can go back into the Settings and change this option at any time. It will remember the option the next time you load Echo.
If there is a device you always want to use with Echo, the best practice is to ensure it is plugged in before you load Echo. This ensures that Echo will always select it. You can go back into the Settings at any time to confirm this.
If you are using a handheld microphone, how you hold and use you microphone is highly important. If the microphone is held too close, or your voice is going directly into it, this can cause sound distortion and poor accuracy. For the best speech recognition results:
Many microphones also have different modes which affect how they receive sound. Your microphone should be in the mode which is best suited for speech recognition. The instructions
below relate to the Olympus RM 4010P. For other models you will need to consult your device user manual.
If you are using a headset or a built-in microphone on a laptop, it should still be kept a consistent distance from your mouth to ensure Echo receives consistent, high-quality sound.
Echo does not require complete silence, but a quieter-environment will generally lead to better results. Noise such as a desk fans, radios and other voices can lower the quality of the sound received by Echo.
Handheld microphones, such as the RM 4010p, are often fitted with noise-cancelling technology to help Echo work in noisier environments. They are also designed to only listen to sound coming from a narrow direction in front of them. This is also why it is important that the microphone is held in the correct position.
