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. Text-to-speech or TTS system converts normal text into Speech.
