Void msg_blk( uint16_t *req, uint16_t *err ) The best solution if that kind of error occurs is hardware reset of the device. In the case of a fatal error all further messages sent to device will cause the error response again. The errors from the device could be divided to two types - fatal and non-fatal errors. Second and third one and more important because it is an error indication. This response is usually received when the system controller identifies that there is insufficient system resource to service the request. First one is a callback that is going to be executed every time we receive message block response. There are three callbacks that can be added to the functionality. One more thing that is not a must but could be helpful is assignment of the callbacks to the library. Initialization of the SPI bus for the communication between the click board and MCU and call the execution of tts_init()that must be executed first before any other function. Datasheet and documentation is provided could be helpful if you want to explore the functionality of the library and click board. Library packed for our compilers can be found on Libstock.įirst of all, like many times before, we want to assign proper pins to our click board. The library covers all functionalities of the S1V30120. In this section we will make a simple example and explain how to use our library. There are also ready made songs that uses DECtalk. So it is an excellent embedded solution.įeel free to explore the links provided in the references, you will find several tutorials on how to make a voice for your robot more natural. DECtalk has the smallest memory footprint in the industry for a full featured, multi-language voice synthesizer. You have to choose the MCU that have at least 45 KB of flash. Reason for that is initialization data that should be uploaded to the click board any we power on the click board.ĭECtalk is the world’s most intelligible TTS synthesizer with the most natural sounding voice. All applications are controlled over a single SPI allowing control from a wide range of hosts. Our click board supports 3.3 V and 5 V power supplies.Īs a cost effective solution the click board doesn't carry it's own MCU and because of that you will need to be very careful when selecting a MCU to use. The S1V30120 contains all the required analogue codecs, memory, and EPSON-supplied embedded algorithms. The TextToSpeech click board that caries the S1V30120 and is a Speech Synthesis IC that provides a solution for adding Text To Speech ( TTS ) and ADPCM speech processing applications to a range of portable devices. The IC is powered by the Fonix DECtalk® v5 speech synthesis engine that can make your robot or portable device talk in US English, Castilian Spanish or Latin American Spanish, in one of nine pre-defined voices. When offering a hardware solution - the TextToSpeech click can be hosted by the MCU and allow the processor on the hardware solution to do the heavy lifting. Today, popular sites are online text to speech. It could have many dependencies on the host OS for example. From the point of a developer the difference is obvious. Software implementation requires development of a solution that is going to be hosted by a PC.
