Wearable word counter
This disclosure generally relates to a portable device. Specifically, this disclosure generally relates to a portable word counter device. The portable word counter device includes a digital microcontroller circuit. The digital microcontroller circuit includes a syllable detector detecting syllables in spoken speech. The syllable detector aggregates a number of detected syllables and applies a syllable to word counted ratio. Based on the syllable to word counted ratio, the syllable detector determines a number of words spoken, and transmits the number of words spoken to a mobile device.
1. A portable word counter system, comprising:
an analog low power circuit, comprising:
an analog input receiver receiving input representative of human speech and transforming the input representative of human speech into a signal,
one or more linear analog filters filtering the signal into one or more frequency bands,
a gain amplifier stage amplifying the one or more frequency bands,
an envelope detector removing frequency spikes from the amplified one or more frequency bands, and
a threshold detector detecting whether or not a voltage or current of the amplified one or more frequency bands exceeds a threshold voltage or current; and;
a digital microcontroller circuit, comprising:
a syllable detector detecting each instance in which the threshold detector detects that the threshold voltage or current is exceeded in the one or more frequency bands as a threshold detection,
wherein the digital microcontroller circuit identifies the threshold detection as a spoken syllable and determines a word count for the number of words received in the input representative of human speech.
2. The portable word counter system of claim 1 , wherein the analog input receiver includes a microphone that receives the input representative of human speech.
3. The portable word counter system of claim 2 , wherein the one or more linear analog filters remove any portion of the input representative of human speech greater than 100 kHz.
4. The portable word counter system of claim 2 , wherein the one or more linear analog filters remove any portion of the input representative of human speech that falls outside the range of 100 Hz to 3 kHz.
5. The portable word counter system of claim 1 , wherein the envelope detector includes a capacitor that removes the frequency spikes from the portion of analog input representative of human speech that are less than 20 kHz and that transforms the analog input into a smoothed waveform.
6. The portable word counter system of claim 5 , wherein the threshold detector includes a voltage comparator.
7. The portable word counter system of claim 5 , wherein the threshold detector further compares at least one of a current and a voltage of the smoothed waveform to at least one of a threshold current and a threshold voltage.
8. The portable word counter system of claim 7 , wherein the threshold detector further generates a threshold detection waveform representative of each instance where the at least one of the current and the voltage of the smoothed waveform exceeds the at least one of the threshold current and the threshold voltage.
9. The portable word counter system of claim 8 , wherein the syllable detector further aggregates the number of threshold detection waveforms generated by the threshold detector and applies a syllable to word counted ratio to determine the number of words received in the input representative of human speech.
10. The portable word counter system of claim 9 , wherein the portable word counter system transmits the determined word count to a mobile device.
11. The portable word counter of claim 10 , wherein the mobile device displays the word count transmitted by the portable word counter system to the mobile device in real-time.
