The product is the development board for the voice MCU HT68V024 which includes 32Mbit Flash. It is extremely easy to use the product with the development platform Voice MCU Workshop. You can edit voices and sentences in the platform, program the edited file to the product using e-LinkPro2 or e-Link, and then connect it to a speaker to play.
The product can play both voice and sentences. Voice refers to various sounds, such as human voices, music, or pre-recorded audio, while sentences are composed of voices, and you can set silence between two voices.
It supports to upload mono WAV files to the Voice MCU Workshop. After editing the voice sources, you can program them to the product or generate a programing file.
The HT68FV024 offers a 32Mbit Flash memory for storing voices, and the storable duration of voices depends on the compression format chosen. The better the audio quality, the more memory it will occupy, resulting in a shorter duration.
On the Voice MCU Workshop, you can select from the following compression formats: PCM, u-law, and ADPCM. Based on the MCU frequency and compression format, you have an additional selection for compressing the file at low, medium, or high qualities.
