You can also try other commands given in library. It has several examples, you can try them all but here we are using a simple code to explain the working. This library is very handy and it has over 1000 words and commands. In the search bar type Talkie and click on the install button. Now the Library Manager will be on your screen. To add the library, go to Sketch->Include Library->Mange Libraries. This library is called as Talkie and it can be added by library manager. The program for this Arduino based TTS is also very easy as the library is available for this. Programming Arduino for TTS (Text To Speech) Now connect the speaker by connecting its negative terminal to ground and positive terminal to the 220♟ capacitor and connect the power supply. The connections are super easy once you make the amplifier circuit.Ĭonnect the power supply to the amplifier circuit and connect the digital pin 3 of your Arduino to 10K resistor and connect the ground of Arduino to ground of the circuit. If you don’t have the exact value of resistors and capacitors then use the close value ones. If you have any confusion about this circuit then check out LM386 Based Audio Amplifier Circuit. Circuit diagram for it is shown below:Ī 100K pot is used to adjust the sound. The amplifier circuit is made by using the IC LM386. Here in this Text to Speech converter, we’ve used an amplifier circuit to reduce the noise and get a clear sound. This step can be achieved by different methods like by recording the human voice for different words/phrases or by generating basic sound frequencies and pile them up as phonemes or by copying human speaking mechanism. The last step is the synthesis of phonemes into spoken voice. This step is really essential so that machine can speak the words as humans do. ![]() these are the sounds that make sentences. The phonemes are the small parts of spoken words i.e. The second step involves the conversion of normalized text into phonemes or phonetic transcripts. This step involves the conversion of the symbols, numbers and abbreviations into words that can be read by the machines like ‘?’ will be converted into “question mark”. The first step in TTS is pre-processing or normalization. We previously used TTS with Raspberry pi in speaking Alarm clock and also converted speech into text in raspberry pi by using Google voice keyboard. Today in this tutorial, we will learn how to make Text To Speech converter using Arduino. You can even find the TTS in Microsoft Word where you set it to speak out the text written in the document. ![]() There are many examples of Text to Speech conversions like the announcements at public transport, the customer care calls, voice assistants in your smartphones, or the navigation menu of any machine. This tech enables the system to speak out the text in a human voice. ![]() Serial.println(myDFPlayer.Text-to-speech or TTS system converts normal text into Speech. Serial.println(F(" forwards or backwards the track")) Serial.println(F(" increases or decreases the volume")) Serial.println(F(" pause/continue music")) Serial.println(F(" stopping reproduction")) Serial.println(F(" To select the MP3 file")) Serial.println(myDFPlayer.readCurrentFileNumber()+1) Serial.println(F("DFPlayer Mini module initialized!")) Serial.println(F("Initializing DFPlayer module. Serial.println(F("DFRobot DFPlayer Mini")) Verifica se o modulo esta respondendo e se o SoftwareSerial mySoftwareSerial(10, 11) // RX, TX Inicia a serial por software nos pinos 10 e 11 The DFMini Player module is shown in Figure 1. The Arduino, for example, will send commands through serial communication with the DFMini Player Module. ![]() It is low cost and low power and reproduces sounds stored on a memory card.īased on this, the module can be controlled via the standalone mode, that is, in this mode, there will only be the DFMini module, a battery to power, the speaker, buttons to control it, and the SD card with the songs.Īnother way to control it is to use an Arduino or another control device. The DFMini Player module is a small music player. Now, we'll learn how to construct the project. Organization and configuration of sound files on the memory card.Basic operating circuit of the DFMini Player MP3.Therefore, in this article we will learn the following points: In all of these systems, we need an MP3 sound reproduction device to connect to the Arduino. Among these projects, we highlight: accessibility for the visually impaired, MP3 music players and the execution of voice sounds by robots, for example. Several projects require sound reproduction to add some kind of functionality.
