Please refer to the attachments for Assessment Instructions and relevant data required to complete this assessment.
– Additionally, there are lectures and tutorial notes attached aswell, which can be used for assignment such as referencing.
Please have in-depth analysis of the data and follow the checklist in the instructions to complete the whole assessment.The assingment instruction sheet also contains an assessment objective, marking rubric and allocation of marks to assist you on whatsections are to be written, and based on the marks, what sections are required to be in-deph.
Here are the FAQ for this assessment answered:
1) I was wondering how to interpret the MDVP diagram. When it comes to determining values for the different components, do I simply look at the corresponding line, or the space between the start of that line and the next.For example, when reading vFo do I just read off the one vFo line or do I look at the space between the vFo line and APQ line?Thank you!– Good question – you just look at the ‘point’ for that parameter. The parameters have been selected from a much larger range of options by the Visipitch user and so the neighbouring ones will be different for each selection. It is simply forming a ‘shape’ between points , but it is the extreme point that matters (may be zero for some).
2) For discussing how data was ‘optimally acquired using VisiPitch with reference to ideal mic setup and recording environment’, do you expect us to briefly mention the 3 voice reports and what was done to achieve these samples.– NO – only ‘ideal’ set up for recording voice in ANY instance, for our purposes.
3) For explaining MDVP, ADSV, and Habitual Pitch ‘with reference to parameters of waveform (frequency cycles, amplitude, duration)’, would it be ok to have a paragraph dedicated to discussing the meanings of each waveform parameter? I understand referring to these within my discussion of the reports, but I don’t think I could do that without first explaining what each of them mean.– You need to explain these waveform features ONCE only to show you understand how/what (acoustic properties) the Visipitch is measuring.
4) I understand comparing the mean F0 and standard deviation, but how I go about comparing ranges? Do I calculate the range for normative data by adding and subtracting the expected SD to the expected mean F0? And then do I discuss if Claire’s mean F0 falls within that expected range? Also, should I even compare her minimum and maximum F0 at all? There is no normative data to compare to, unless the values to compare to are the max and min values of the ‘expected’ range?– The Standard Deviation gets added EITHER side of the mean to get the normal range (within 1 SD).
5) In relation to the MDVP, are we supposed to find a number value for each parameter? Additionally, how many of these parameters are we supposed to discuss?–On the MDVP Diagram where the ‘points’ are at zero (0) for DUV and DSH, this represents a zero (0) result here – they were still measured, you must interpret this.
6) And when it says to explain the data with clear reference to the parameters of the waveform (frequency cycles, amplitude, time/duration), what waveform is this referring to? Have we been given one because I’ve looked through all the resources but couldn’t find one?– This does not mean a particular waveform, but rather your understanding of how these parameters relate to a waveform, amplitude, duration – bring meaning to the parameters – what aspects of ‘sound’ are they measuring?
7) when we analyse the habitual pitch report and compare it are you wanting us to just discuss the mean and standard deviation or the min, max, range and vFo as well?– Compare the mean Fo & SD to the norms. You can comment on the range if you have done some relevant research. Yes, you must show you know what the vFo is and what the result means. Remember you can cluster MDVP parametera if they have same result but at lest one sentence is required for each parameter giving an explanation/definition.63488910 minutes agoBelow is a checklist:– Begin with an overview of the adult client’s relevant history based on your interpretation of the background information, with reference to activities and participation– Discuss how the data was (optimally) acquired using the Visipitch, with reference to the ideal microphone setup and recording environment– Explain your understanding of mean fundamental frequency (Fo), MDVP and ADSV data provided, with clear reference to parameters of the waveform (frequency cycles, amplitude and time/duration)- This is the main part of Case Study, therefore, more information required.– Analyse the mean fundamental frequency (Fo)/habitual pitch, MDVP (all parameters featured in report) and ADSV data provided, in comparison to normative data for age and gender- This is the main part of Case Study, therefore, more information required.– Summarise the results above – Identify concerns for the client linked to the literature/evidence base
