A method for extending the life of the attachments that attach blades to rotors, particularly for aerojet engines. Such a method is notable in that it employs intensive ultrasonic peening of the grooves and of the roots of the blades, this peening being performed with an Almen intensity at least equal to F8A, so as to increase the compressive prestress in the contact surfaces without increasing the roughness of these surfaces.

The method as claimed in claim 11, further comprising the steps of: f3) determining a difference between the first time stamp and the second time stamp; and f4) adding or subtracting the difference to time stamps that occur after the second time stamp. 13. The method as claimed in claim 9, further comprising the step of editing the textual representations of the phrases. 14. A method for transcribing multiple independently recorded files of digitized speech into a single document, the method comprising the step of: a) accessing the multiple independently recorded files of digitized speech data, wherein the multiple independently recorded files represent multiple speech recordings that were independently recorded into individual files within a single recording session and each individual file of the multiple files is associated with a particular user; b) outputting, to a speaker, an audio representation of a first phrase from a file of the multiple files; c) adjusting an offset time associated with the first phrase, wherein the offset time indicates a time difference between a beginning of the recording session and a beginning of the file; d) transcribing the multiple independently recorded files by applying a speech-to-text conversion technique to digitized phrases within each of the multiple independently recorded files in order to convert the digitized phrases to textual representations of phrases, wherein the digitized phrases represent segments of the digitized speech data; and e) storing the textual representations in a time-sequential order in a single file, resulting in a single sequence of textual representations of the digitized phrases from the multiple files. 15. The method as claimed in claim 14, further comprising repeating the steps of outputting and adjusting until the method is interrupted. 16. A transcription apparatus for transcribing multiple independently recorded files of digitized speech data into a single document, the apparatus comprising: a processor that accesses multiple independently recorded files of digitized speech data wherein each of the multiple independently recorded files represent multiple independent speech recordings that were recorded within a single recording session and each of the multiple independently recorded files is associated with a particular user, transcribes the multiple independently recorded files by applying a speech-to-text processing technique to digitized phrases within each of the multiple independently recorded files in order to convert the digitized phrases to textual representations of phrases, and stores the textual representations in a time-sequential order in a single combined file; and a memory device for storing the text representations. 17. The apparatus as claimed in claim 16, further comprising a user interface for enabling a user of the apparatus to select the multiple files to be transcribed and to edit the combined file. 18. The apparatus as claimed in claim 16, further comprising: a digital-to-analog converter for converting the digitized speech data into analog speech signals; and a speaker for outputting the analog speech signals. 19. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of: a) accessing the multiple independently recorded files of digitized speech data, wherein the multiple independently recorded files represent multiple speech recordings that were recorded within a single recording session and each of the multiple independently recorded files is associated with a particular user; b) tra
