MP3 speech files for use in clock projects

In recent post I’ve posted about Using Text to Speech online tools to create audio files for Arduino projects and Batch processing files with Audacity. I have a couple of projects that use speech alerts and one of those is a speaking clock. It announces the time at the press of a button, but more helpfully announces the hour, when it is time to get up and when to have morning tea and lunch.

While I don’t think the Arduino code is in a fit state to share I’ve uploaded the audio files to Github for anyone to use in their projects. There are two versions of of the files:

  1. French Celine created with Online Tone Generator. These are the files I am currently using in my clock.
  2. British Amy created with TTSMP3. An alternative set I made to test TTSMP3

I use French Celine in my project. Here are a couple of examples of what they can do when joined:

  1. A problem I have been trying to solve for a number of years. There was a time when MAC had a program that would play an MP3 file on the hour, or quarter hour or any combination. It also had the programability to make it play a random MP3. So, you could essentially have a folder of random MP3 and every 15 minutes the computer would play a random sound. I loved it. It was hysterical. The programmer has stopped updates. Looking at your blog and your knowledge, you might have suggestions for me to build a box that would do the exact same thing. Am I correct? Any suggestions?


    1. Hi. Although I’ve had several iPads I’ve never had a mac, but I remember reading back in the 90’s that macs quacked every now and then. I presume this is the same thing. It shouldn’t be too difficult to design and build something that does that with an Arduino module, for example a Nano and one of these MP3 modules. If you are not concerned about it making the sound at defined times, for example on the hour then it would be simpler as a Real Time Clock module would not be required. You could have it play a random sound at either every 15 minutes or so or at random times. I would look at setting the next play time using millis timer and then play the track and then set the next play time.

      If you want it to play on the hour and set intervals between the hour then you are only a step away from building a clock. It’s just missing a display.


      1. Thanks for responding!! Okay, so if I were to purchase and Arduino Nano… that would be a start. I really want to do this and would love to play around, but nothing is more frustrating to me than starting a new hobby and finding out I didnt reallllllly get what I needed. So, Arduino Nano. Then I assume I can get into the terminal… and I would wager there is coding somewhere for what I want.. or at least basis for it. I could set it to play a random wav file from a drive of thousands of files and.. I could set it to play at specific intervals.. ( it also helps me track time passing ) and … lol.. yes.. macs could quack. They ‘had” about seven basic sounds you could set as notifications. The app I am referring to was basically a “cuckoo clock” from a programmer that allowed you to choose the sound and how often it repeated. I really miss my computer randomly spitting out phrases…


      2. Ideally it sounds like software for your computer to do this would be the best option. However, Arduino is an alternative way. If I understand correctly, you have not used Arduino before so I’ll provide a bit more info about that. Sorry if you already know this. Arduino consists of programming software and standalone hardware. The hardware is based around cheap microcontrollers that are supplied on a development board that have additional support parts to get them up and running fairly easily. Included on many boards including the Nano is a USB socket to allow it all to be easily programmed by a Mac, Windows or Linux computer.

        They were designed to make it easier to program to allow more people to make things. Many people that have done programming before are surprised at how quickly they can get going with it. I expect anyone that has never programmed before to find it a bit more challenging but still doable.

        The Arduino Nano doesn’t have a built-in clock, but it does have a timer that begins counting up as soon as it is powered. The timer counts in milliseconds and while it is useful for many things it is not as accurate as a clock. I’ve pasted in a simple program below for the Nano that uses the timer to play a random track every set number of minutes. The code may give you an idea if this is the sort of thing you want to take on or not.

          const byte infoReq = 0x00;      // Get info back from module - 0x00 = no info, 0x01 = return info
          const bool isDebug = false;     // Debug mode - Off in this sketch
          const byte endByte = 0xEF;      // Fixed end Command
          // Calculate the checksum
          unsigned int checkSum = -(versionByte + dataLength + Command + infoReq + Param1 + Param2);
          // Construct the command line
          byte commandBuffer[10] = { startByte, versionByte, dataLength, Command, infoReq, Param1, Param2,
              highByte(checkSum), lowByte(checkSum), endByte };
          // Send to player
          for (int cnt = 0; cnt < 10; cnt++) {
          // Delay needed between successive commands

        I've added in lots of comments to provide info about each bit. In this example delayTime and numberOfTracks need to be changed to the number of minutes between each play and the total number of tracks in the SD card folder.

        Tracks need to be placed on a Micro SD card in a folder and each track needs to start with a 3 digit number starting with 001. The rest of the filename is not important. The DFPlayer just looks at the first three digits.

        This creates a standalone project. If you are still interested, I recommend having a look more at Arduino. I usually buy parts from eBay and I expect the Nano and DFPlayer would cost around US$10 - $15 for the two. A good speaker can cost more but you may already have one of those.


      3. WOW.. thank you for all the information. Very helpful and I had no idea I would get this much help via a blog. I will check it out. It would be nice to have software for my computer, but the arduino would make it much more portable than a desktop lol. Okay, now Ive got some steps to take. Thanks again.. Ill keep you apprised.


      4. Im pulling the trigger on this lol.. I have no idea how the two parts meld together.. but.. I trust they will. Excited to learn a new craft…

        NEW – Arduino Nano V3.0 ATMEGA328P CH340 16Mhz ** NEW with USB-C port !! **

        DFplayer Mini MP3 DF Player Module Module Music Audio SHI O8F8 J9K Voice V9B1


      5. Good luck with the project. I’ve not used the version of the Nano with a USB connection but I don’t expect you should have any issues with it and I expect you already have a cable to fit it whereas the mini USB cables are not very common any more.

        Other than the DFplayer module and a speaker, you will also need a micro USB card to store files and a 1K resistor. The resistor is for the data control line between the Nano and the DFPplayer and its purpose is to reduce the current and prevent noise from the Nano coming through to the speaker. As well as a resistance value, resistors also have a maximum current rating. The smallest is usually .25W which is fine. A 1K .25W resistors are usually sold in lots of at least 25 for about $2.

        The wiring will be similar to this tutorial except for:
        – The wire between the Nano D10 and the DFPlayer (green wire) is not needed.
        – The yellow wire (TX) should be connected to D9 on the Nano instead of D11 to use the demo code I supplied.


      6. So, nano was delivered.. the player wont appear till mid oct. ( supply chain?) Nano mentions a static warning.. and dear lord, its been a life time since I’ve soldered. I need to get a gun to do it. lol.. starting to feel a bit in over my head and yet.. it looks pretty simple. How static sensitive is this thing?


      7. Good to hear the Nano has arrived. From what I can find online I don’t think Nanos are particularly prone to static as they have inbuilt diodes to protect against that, but I always avoid touching the pins too much. Most get destroyed in other ways such as trying to use the output pins to drive a large load, or in my case I’ve had them connected up on my desk and a metal object has slid underneath shorting out pins.


      8. I havent forgotten this thread… apparently there is a serious supply chain issue with the player.. still waiting. In the meantime I am watching youtube videos to remember soldering tips.


  2. hmmm didnt post… I’ll try again. So… all the parts have arrived, now for the daunting task of making the time to put it together lol


    1. Hi David, sounds like the fun is about to begin. If you get stuck you can post questions here, or if you prefer I can send you my email to avoid it all being public.


      1. lol..Im an actor… being embarrassed in public is second nature.. but email might simplify. I appreciate all the free knowledge you have provided, I dont want to push it 😉
