Examples

Example of Phoneme Speech (download and simulation) Speech The Phoneme based speech can be output on Microcontroller hardware using a number of methods.

PWM - Outputs using a single PWM pin, a simple external RC low pass filter can be used to remove the high frequency PWM to create an audio signal.

Parallel - Outputs using a 8-bit port, a simple 8-bit R2R DAC circuit can be used to combine the bits into an audio signal.

Other - A third option is to use the ReadByteFromPhoneme macro to pull out the phoneme values a byte at a time which can be used to pass on to an external DAC etc.

Another example of Phoneme Speech, taking a reading from an analogue channel and speaking the Voltage. (download and simulation) Talking Volt Meter Example of Real Speak Speech (simulation only) Speech2 Adding additional language packs to the Real Speak engine.

	ReadPhonemeLength
Function to return the number of bytes used in a single phoneme array.
- STRING	Phoneme
Specifies a single Phoneme
- UINT	Return

	EnableOutput
Sets up the output to allow the speech data to be streamed out.
- VOID	Return

	DisableOutput
Disables the output to prevent any buzzing etc while not speaking.
- VOID	Return

	ReadByteFromPhoneme
Reads a single byte value from the specified phoneme data array. This function will not simulate correctly as it requires C style pointers.
- STRING	Phoneme
Specifies a single Phoneme
- UINT	Idx
Specifies the position within the Phoneme
- BYTE	Return

	OutputPhoneme
Streams a single Phoneme or string of comma seperated Phonemes. OutputPhoneme("OY") OutputPhoneme("OY,AY,OY")
- STRING	DataString
- VOID	Return

Property reference

	Properties
	Phoneme Selection
Selects which phonemes are included in the embedded firmware
	Phoneme Data Set
Specifies if the phonemes used are based on the inbuilt phoneme wav files set or a custom file set. To create your own phonemes, copy the wav files from the components directory, then overwrite the phonemes you wish to edit. Phonemes are re-parsed on simulation start and on compile to C.
	Pitch (Hz)
The frequency at which the phoneme data is output in bytes/samples per second.
	Phoneme Data Size
The number of bytes used by the current phoneme selection
	ROM Size
The maximum number of bytes available in the ROM of the selected target device. The ROM has to contain the program as well as the Phoneme data.
	Base ROM Address
The address in ROM to place the phoneme data. It is recomended to always use the suggested address as this will place the phonemes right at the end of ROM and away from the program.
	Suggested Address
The ideal address to allow all the selected phonemes to fit into the end of the ROM memory Thereby allowing the maximum space for the user program.
	Output Mode
Determines how the phoneme data is going to be output.
	PWM Pin
PWM channel selection used to determine which PWM peripheral to stream the Phoneme data to.
	PWM Pin
The actual port pin assigned to the selected PWM channel.
